Week - 3 Drop test Challenge

Objective:

Cell phone drop test is conducted by creating necessary input cards

Steps:

1. Reducing the parts in order to simplify the analysis here i have deleted the bottom solid plate. So there all only two parts SOlid (mobile)part and the shell

2. Added two section shell and solid ,thereby shell thickness is 5 mm is defined on the card.

3. Creating the material card ,here i have created two cards one is rigid MAT-020 and other one is piecewise linear plasticity MAT- 024
4. AUTOMATIC_SURFACE_TO_SURFACE contact has been defined betwen the plate and cell phone.

5.INTIAL card has been used to define the velocity of the cell phone to be impact on the plate . velocity of -1 E04 has been given to the nodes

6.Using BOUNDARY (SPC) card we can fix all the nodes of the plate.

7.control Termination card has been used to determine the end tIme seconds, here i have defined 0.03

8. In order to plot the results ASCII output and binary plot Keywords are used

RESULTS:

9.Maximum stress is observed on corners of the mobile phone

10.Inorder the internal energy and kinetic energy are plotted for the model
