1. Introduction

ATCP Physical Engineering equipment and products have been projected and manufactured

to provide a long-lasting and top-rated performance. This Installation and Operation Manual

contains all necessary information regarding the use and maintenance of this equipment.

Carefully read this manual before using the equipment. Improper use

may damage the product and compromise its performance.

2. Definitions

Impulse Excitation Technique: The Impulse Excitation Technique is a non-destructive test

to determine the elastic moduli and the damping of materials using their resonance

frequencies. This technique is described in the ASTM E1876 and correlated standards.

Resonance Frequencies: Natural frequencies of vibration of a sample.

Elastic Modulus: Elastic modulus is defined as the slope of the stress-strain curve at the

elastic region, as described by Hooke’s Law.

Damping: Damping is the phenomenon by which mechanical energy is dissipated in dynamic

systems. It is directly linked to the presence of defects and the microstructure of a material.

3. Features and applications

SA-BC Support is an apparatus employed to hold samples to non-destructively measure

Young’s Modulus and damping of materials through the Impulse Excitation Technique,

following the ASTM E1876 and correlated standards. SA-BC Support was developed to be

used alongside Sonelastic® Solutions.

SA-BC Support allows rectangular and cylindrical samples to rest on the nodal lines of the

fundamental flexural vibration mode (for a sample of length L, these nodal lines are 0.224L

distant from the ends of it). Based on the size and weight of the sample to be tested, this

support offers a practical system to adjust the distance between the SUPPORT-CABLES, as

well as the tensile stress applied on them. SA-BC Support also allows tests based on torsional

and longitudinal vibration modes for bars and cylinders.

To employ the Impulse Excitation Technique with greater precision and practicality, SA-BC

Support may be combined with IED AUTOMATIC ELECTROMAGNETIC IMPULSE DEVICE and

STURDY TRIPOD.

7.2 Placing the sample

The sample should be symmetrically supported and placed over the SUPPORT-CABLES, with

those at a distance of 0.224 L from the sample ends (L is the length of the sample). For

instance, if a sample’s length (L) is 100 mm, the SUPPORT-CABLES should be positioned at a

distance of 22.4 mm from the ends. The positions of 0.224 L correspond to the nodal lines of

the flexural vibration mode.

Support and typical positioning for a cylinder.

Support and typical positioning for a bar.

The corresponding distance calculation of 0.224 L is automatically generated and informed by

Sonelastic® Software. Markings on the sample are generally done by using a pencil and a ruler

or caliper ruler. The SUPPORT-CABLES position is adjusted by dislocating the fastening

terminals.

8. Installing the equipment

8.1 Requirements

- The workbench must be flat and leveled with a free gap of at least 60 x 120 cm (depth

and width). This gap should be enough to fit SA-BC Support, samples, computer and

optional items that these may be combined with.

- A 127 or 220 VAC three-pin ground wired electrical mains plug. This pug is needed to feed

the computer and other optional items that may be combined with the use of SA-BC

Support.

The equipment installation consists of positioning it over the workbench and coupling the

MICROPHONE to the VERTICAL BASE or STURDY TRIPOD. Following that, choose the

SUPPORT-CABLES and put them together.

8.2 Typical arrangements

Typical SA-BC Support arrangements are presented next.

[6]

Configuration: Manual. Excitation: Manual torsional mode. Sample: Heavy cylinder.

Microphone: Using a STURDY TRIPOD for signal acquisition under both torsional and flexural modes.

Impulse Device: Manual and of medium impact.

[7]

Configuration: Automatic.

Impulse: Automatic. Sample: Medium-sized.

Microphone: Using a STURDY TRIPOD for optimum position of the flexural mode.

Impulse Device: IED Automatic Electromagnetic Impulse Device with a HEIGHT-ADJUSTING DISC.

Note: In the typical arrangements presented, the optimum support form for the flexural mode

is also proposed for torsional and longitudinal modes. Nodal lines and the ideal support for

these vibration modes, however, do not match the ones for the flexural mode. The longitudinal

mode, for example, is not sensitive to the cables supporting positions (when faces are free)

and the sensitivity of the torsional mode is less than 1%. As a result, it is possible to use the

flexural mode boundary conditions to characterize the longitudinal and torsional modes

efficiently, without compromising the results.

Attention! Before using SA-BC Support, verify if it has been fitted with

its four rubber feet and that those are secure (not wobbly) on the

workbench. If any of its feet is not flat on the workbench, readjust it

until all feet are securely placed and flat on the workbench.

8.3 Mounting the MICROPHONE in the VERTICAL BASE and STURDY TRIPOD

VERTICAL BASE:

Step 01: Insert the MICROPHONE in the VERTICAL MOUNTING BASE ensuring the wire

goes out through the side opening, as pictured bellow:

Step 02: Press the BASE against the MICROPHONE until it feels coupled and secured to

the BASE.

STURDY TRIPOD:

Step 01: Insert the MICROPHONE in the STURDY TRIPOD microphone clip, as pictured

below:

Step 02: Slide the MICROPHONE into the clip until the whole microphone frame is fully

secured, then place its cable over the STURDY TRIPOD inner tube.

Step 03: Connect the MICROPHONE to the computer’s audio input.

8.4 Replacing the SUPPORT-CABLE set

The thinner the SUPPORT-CABLE, the smaller is its interference on measurements. However,

observe the maximum weight than can be held by each of the two SUPPORT-CABLES

available. SA-BC Support is factory supplied with a Ø1.20mm SUPPORT-CABLE set, which

Page 16: Installation and Operation Manual - sonelastic.com · (L x D) - 100 x 50 - 150 x 75 - 200 x 100 mm - 300 x 150 mm - 500 x 50 mm Square Section Bar

Sonelastic® Solutions SA-BC Adjustable support for bars and cylinders

Pág. 16 de 25

would have already been installed (this is the recommended cables to be used with samples

weighting between 10 and 30kg). To replace them for the Ø0.70mm SUPPORT-CABLES

(recommended for samples weighting up to 10kg), follow the steps described next:

Step 01: Turn the SUPPORT-CABLE tightener anti-clockwise until the SUPPORT-CABLE is

completely loose. Hold by the hook when turning the tightener to stop the

cable from turning together with it;

Step 02: Disconnect the SUPPORT-CABLE ends (eye nuts) from the respective hooks

(tightener terminal and fixed terminal);

Step 03: Repeat the previous steps to uncouple the other SUPPORT-CABLE;

Step 04: Hold the new SUPPORT-CABLE to be used and couple the eye of one of its ends

to the fixed terminal hook;

Step 05: Maintaining the new cable under a slight tension, place it on the tubes,

ensuring it fits perfectly the chute of each one of the three supporting sleeves

of the SUPPORT-CABLE. Next, couple the other cable eye nuts to the tightener

terminal hook;

Step 06: Holding the hook as illustrated in Step 01, turn the tightener clockwise so that

the new SUPPORT-CABLE is completely tensioned;

Step 07: Repeat the previous steps to fit the other SUPPORT-CABLE.

For light samples (weighting up to 10kg), tension the SUPPORT-CABLES until fully stretched.

The sliding support tube allows the fine adjustment of tension on the SUPPORT-CABLES. For

heavy samples, adjust the tension on the cables so that, when the sample is placed over

them, it will only go down about 15 mm from its initial position, as pictured below:

Page 17: Installation and Operation Manual - sonelastic.com · (L x D) - 100 x 50 - 150 x 75 - 200 x 100 mm - 300 x 150 mm - 500 x 50 mm Square Section Bar

Sonelastic® Solutions SA-BC Adjustable support for bars and cylinders

Pág. 17 de 25

The tension on the SUPPORT-CABLES should be reduced if heavy samples shift down less

than 15 mm.

8.5 Installing the IED AUTOMATIC ELECTROMAGNETIC IMPULSE DEVICE

Before installing the IED AUTOMATIC ELECTROMAGNETIC IMPULSE DEVICE (Controller and

Device) read its own Instructions Manual.

9. Equipment operation

After following the steps in 8 – Equipment Installation, your SA-BC Support will ready for use.

9.1 Positioning the sample

To be able to carry out a fast and precise characterization of samples using SA-BC Support,

read carefully the following steps:

Step 01: Install the equipment according to the characterization and size of the sample

(see 8 – Equipment Installation);

Step 02: Using a ruler or a caliper ruler and a pencil, trace nodal lines on the supported

face and on the sides of the sample. These lines should be 0.224 L distant from

the ends being L the length of the sample (see 7.2 - Placing the sample);

Step 03: Shift the sliding support tube until the opening distance between this and the

fixed supporting tube is greater than or equal to the width of the sample. The

positioning adjustment of this tube is not critical for the measurement result

and may also be used to adjust the tension on the SUPPORT-CABLES;

Step 04: Dislocate the tighteners, terminals and sliding support sleeves together with

their respective SUPPORT-CABLES until the distance between them allows to

support the samples exactly by their nodal lines (0.224 L);

Step 05: Place the sample over the SUPPORT-CABLES ensuring that the nodal lines

traces are precisely aligned with the cables under it.

After completing these steps, the sample should be correctly supported and positioned for the

characterization.

Note: To measure the torsional mode in rectangular bars, it is necessary to trace nodal

lines that are at a distance of 0.32 L for acquisition and excitation. For more details, check

10 - Acquisition and Excitation Modes.

9.2 Positioning the MICROPHONE for acoustic signal acquisition

Step 01: Mount the MICROPHONE in the STURDY TRIPOD microphone clip or in the

VERTICAL MOUNTING BASE, as described in 8.3 –Mounting the MICROPHONE

in the Vertical Base and on the STURDY TRIPOD;

Step 02: Adjust the height or distance of the MICROPHONE, so its acquisition sensor is

at a distance of approximately 1 cm away from the face of the sample, as

illustrated below. Note: The distance is not critical for the results;

Step 03: Position the MICROPHONE as desired. It may be in line with the center of the

inferior face of the sample, when focusing on the flexural mode; in line with

and above the sample, when focusing on the longitudinal mode; or to the side

of the inferior face (near the SUPPORT-CABLES at the 0.32 L position), when

aiming to obtain both flexural and torsional modes.

Note: For more details on the correct positioning of the MICROPHONE, check 10 – Acquisition

and Excitation Modes.

9.3 Positioning the IED AUTOMATIC ELECTROMAGNETIC IMPULSE DEVICE

Step 01: Check if the Impulse Device is directly below the center of the inferior face of

the sample if the focus is on the flexural mode; or to the side of the inferior

face (0.32 L) to measure flexural and torsional modes.

Note: For more details on how to correctly position the Impulse Device, see 10 – Acquisition

and Excitation Modes.

Step 01: Turn the adjusting nut of the Impulse Device clockwise and anticlockwise to

allow the vertical movement of its tip. Adjust the position so it remains

approximately 3 mm away from the sample, as pictured next:

Page 20: Installation and Operation Manual - sonelastic.com · (L x D) - 100 x 50 - 150 x 75 - 200 x 100 mm - 300 x 150 mm - 500 x 50 mm Square Section Bar

Step 03: Configure the intensity of the shock from the Impulse Device against the

sample (see more information in the Instructions Manual that comes together

with IED Sonelastic).

Note: All information regarding the IED AUTOMATIC ELECTROMAGNETIC IMPULSE DEVICE

has been described in detail in its Installation and Operation Manual.

Attention! When dealing with heavy samples, ensure safety cables are

always positioned close by the SUPPORT-CABLES to avoid chances of

samples falling over the hands of the user in the case of a SUPPORT-

CABLE rupturing.

The next table provides more information to the previous one, but focusing on cylindrical

samples.

Flexural Mode - I

Excitation from above and

signal acquisition from below,

both aligned with the center

of the sample.

Cables positioned at 0.224 L.

Flexural Mode - II

Excitation from below and

signal acquisition from above

both aligned with the center

of the sample.

Cables positioned at 0.224 L.

Longitudinal Mode

Top-centered excitation and

signal acquisition from

opposite sides of the sample.

Cables positioned at 0.224 L.

Flexural + Torsional

Modes - I

Excitation from above and

signal acquisition from below

from opposite sides and

ends.

Cables positioned at 0.224 L.

Flexural + Torsional

Modes - II

Excitation from below and

acquisition from above from

opposite sides and ends.

Cables positioned at 0.224 L.

Considering the arrangements presented to the signal acquisition of torsional and longitudinal

modes, positioning the SUPPORT-CABLES at a distance of 0.224 L is not ideal and it may

compromise the Damping measurements, however it has minimum influence (< 0.5%) when

determining Young’s Modulus.
