Week 11 Car Crash simulation
Objective of challenge: To perform a Explicit dynamic analysis of a Car Crash, a parametric study using 3 different values of thickness for the car body. Need to apply the same conditions as per the video. Find out total deformation and Equivalent stresses acting on the model.
Simulation setup configuration as follows:
1. Model as follows
2. Part names are specified for 3 cases as
3. Material applied for 3 cases as
4. Symmetry and Connections are configured for 3 cases as
5. Mesh size is configured for 3 cases as
6. Analysis settings are configured for 3 cases as
Explicit dynamic simulation results are as follows:
