Week 11 Car Crash simulation

OBJECTIVE :-

To perform a parametric study using 3 different values of thickness for the car body.
Analyse the total deformation and Equivalent stresses acting on the model

PROCEDURE:-

Open ansys work bench R2
selece explicit dynamics
rename the work if it necessary
select stainless steel non linear material from engineering data source
import geometry
rename its part properly
select stainless steel non linear material and assign it for car body
click parameter box provided in definition section ,input .3 mm as thickness for first case
insert symmetry in model section ,insert symmetric region ,select end side of wall as its scope
insert symmetric region ,select all edge of car body by edge filter tool
in connection section ,delete default contact ,keep body interaction as it is
in mesh section ,click generate mesh ,it any further adjustment needed insert sizing and adjust element size
in anlysis section input 0.001 s for end time
insert fixed support ,select its scope by selecting some part from back side of the car body
insert displacement ,select one side of wall as its scope ,input zero for x and y axis ,input 500 mm through tabular data for z axis
insert total deformation ,equivalent stress and equivalent strain from solution section
run solve

RESLUT:-

TOTAL DEEFORMATION:-

EQUIVALENT STRESS:-

EQUIVALENT STRAIN:-

PARAMETER VALUE :-

TABULATION :-

CONCLUSION:-

Total deformation is reduces with increasing thickness of car body
equivalent stress is maximum for car body having thickness of 0.5mm is 5006.34 MPa
equivalent strain less in 1 mm thickness body and is equal to 0.02366
