Assignment 3-2D Element Formulation Challenge

REPORT:

AIM:

Comparison of results with base simulation and improved shell element properties

1.Using the crash beam file from the previous assignment, change the run time to 55 ms.

2. Change the number of animation steps during simulation to a minimum of 25 and a maximum of 60.

3. Run the base simulation without any modification to element properties.

4. At the end of the simulation, do the energy error and mass error checks and determine whether the results would be acceptable.

5. If acceptable, Plot rigid wall forces, internal energy, hourglass energy, contact energy, and total energy of the simulations.

6. Change all the shell elements properties to recommended properties, save this as separate, rad files, and run the simulation.

7. Follow steps 5 and 6.

8. Create a brief report comparing all the results from steps 5 and 6 for both simulations.

9. Comment whether there is any change in the results and why there is any change in the result.

CONCLUSION:THE CAMPARISION BETWEEN THE TWO MODELS WERE STUDIED.
