Week - 3 Drop test Challenge

CHALLENGE

Aim- to create a simulation of drop test to Mobile phone with given meshed .K file

Procedure-

Import the .K file to LS prepost
The file consists of three parts, but for drop test only two files are required for simulation
Apply boundary spc for base plate in all Dof
Apply set for Mobile part nodes and titled as Mobile

After applying set to mobile nodes, by Initial Keyword added velocity of 15 m/s in –Z direction
Add MAT_RIGID keyword to with the properties of steel for base

Add MAT_PEICEWISE_PLASTICITY for material of mobile with material properties of polycarbonate RO-0.0012,E=2600,Pr-0.3142,Etan-120
Add two SECTION_SOLID Keywords for both Mobile and base parts
Assign Mat_id and Sec_id in Part Keyword for both Mobile and Base
Apply Contact Keyword (SURFACE_TO_SURFACE) add mobile as Slave and base as Master
Add CONTROL_TERMINATION KEYWORD as 3sec
Add DATABASE keyword by applying ascii(glstat) and d3plot timestep as 0.1 sec
Save and solve in Launch manager

OUTPUT-

The given task had been Completed and it runs in LS-DYNA. The simulation has been done and both d3plot and glstat outputs are listed down
Plots of Internal and kinetic and total energy are listed below
