## Test your FEA skills! How much do you know about FEA?

I've prepared a few questions for you! If you are quick it will take you around 2-3 minutes.

## 1. L-section dilemma!

This is a simple piece of L-section. One end is fixed, while the other is loaded as you can see below. What is the correct von Mises stress distribution?

## 2. Symmetry problem

You have this nice compressed element. Can you use symmetry through the middle in the analysis?

## 3. Load on a cylinder

You are testing a cylinder in a hydraulic press. If it is uniformly supported at the bottom (as below) it doesn't matter if you use load or enforced deformations in your linear FEA model - the stress distribution will be correct. What if the cylinder would be supported on 4 small supports instead of entire circumference?

## 4. Bolt modeling

When it is reasonable to model a bolt as a beam connected with RBE2 elements to the circumference of the opening in a plate assuming you are interested in stress distribution in the pleat near the bolt?

## 5. Mesh size

You used 3 mesh sizes A, B and C and you read stress for each of them. You want to have an outcome within 10 MPa accuracy. Which mesh size should you use?

## 6. Mesh size

You analyzed the same problem with more element sizes. Which mesh size shuld you choose for 10 MPa accuracy?
