Week - 3 Drop test Challenge
AIM- To perform drop test of cell phone using ls dyna solver and give detailed report
procedure
open the keyword file which was given in the question
the file consists of a mobile phone model and a rigis wall solid element and shell element i this we are going to delete the solid wall element
because the solid element takes more time than shell element while solver runs
as we know the file consist of 2 parts we will assign different material properties to both the wall and cell phone
rigid wall

cellphone

there are two sections which we need to create
for wall

for cell phone

applying section and material to the part in the file
rigid wall

cell phone

after this we need to introduce velocity go to the keyword search and select all you will find every thing which we need to provide to the model
initial velocity
introduce the velocity to the cell phone

now we will introduce contact to the model

now we need to add energy card to the model

then we need to add the time which is termination closed time

for animation we need to introduce binary_d3plot card to the model

we need to create ascii option card to get output like global data, material engine and rigid wall forces



please select only these three
now check the model for any waring or error

having warning is okay but weneed to clear all un referred things or things with error

now run the ls dyna solver


once the termination is finished normally open the d3plot to see the animation
