# Foundations in Structural Nonlinearities using Ansys Mechanical - Simulation Quiz 2

### Static Structural Analysis of Two Blocks in Contact

Contact interaction between parts needs to be considered in most engineering designs, and the effects of friction can also play an important role. In this simulation exercise, we will look at a simple problem of a block being pressed against a base and then moved a certain distance while maintaining the compression. To incorporate the real-world scenario, we will perform a Static Structural Analysis with frictional contact between the parts.

Follow the instructions to set up the simulation and get results BEFORE starting the quiz. Download the instructions and necessary simulation files from here.

What is the maximum equivalent stress experienced in the entire model at the end of Step 2 (time=2)? Select the option that is closest to the value you obtained.

2 / 10

Review the frictional stress contact results at the end of Step 2 (time=2). Review all options, and select the option that is correct.

3 / 10

Consider a separate situation where the coefficient of friction is decreased to 0.0. (Do not re-run such a simulation.) What change is expected to occur in the maximum frictional stress in the contact region at the end of Step 2?
