What am I trying to Solve
Where are my weak points?
Is this material strong enough?
Is this thing too beefy?
Is this joint going to hold up?
What type of study should I use?
Linear Static Study
Before You Begin
Your Source for Engineering Design Solutions
Static
Loads applied uniformly and constantly
No impact or changing loads
Mass
Pressure
No Rigid Body Motion
Your Source for Engineering Design Solutions
Linear
Are all loads in the elastic range
Will my model return to its original shape
after loading
Your Source for Engineering Design Solutions
Small Deformation
No large displacement problems
Materials that will not break if bent too much
Geometry that causes large displacement
Your Source for Engineering Design Solutions
Linear Elastic Study
Static
No motion
Constant Loading
Linear
Are all loads in the elastic range
Model will return to its original shape after
loading
Small Deformation
Your Source for Engineering Design Solutions
What to do with the numbers
See how much the part displaces under loading
Failure Criteria to see if material is yielding
See which areas of the model carry load for material optimization.

What is FEA?
Numerical Solving technique
Breaks part up into small chucks (elements)
Solves for each small chunks
Compare Values to material properties
Determine material failure
