SDC Verifier implements:

• Individual Loads;

• Load Sets;

• Load Groups.

A lot of loads and

combinations should

be checked according to

standards.

Standards and Custom Checks

Fatigue check according to different methods and

standards;

Plate Buckling according to ABS and DNV standards;

Custom Checks (anything can be checked as long as the

formula is known);

Custom Checks Examples;

API RP 2A Tubular Joint Check;

2014-05-15



Fatigue Check example

(mean stress correction)

For single stresses

Fatigue Allowable Stress Design (Goodman relation)

Combined

Allowable Stress depends on classification

Element Group 6 more

than 2 millions cycles

K4 welds example

Used by standards as DIN 15018, FEM 1.001, NEN 2018/2019 and FKM

2014-05-15



Allowable Stress vs Kappa

Weld Class K3 - Green Weld Class K2 - Red

Utilization Factor (Smax/Sallow)

Notch group/Weld Class

Allowable Fatigue Stress depends on Weld Class and Kappa=Smin/Smax

Fatigue Example

Results over sections. Values

which do not pass the check

are highlighted in red.

Automatically convert element

stresses into plate direction.

Automatically recognized

dimensions of plates
