Week 11 Car Crash simulation

Aim:- To perform car crash analysis in Explicit Dynamics

Objective:-

perform a parametric study using 3 different values of thickness for the car body( 0.3mm , 0.5mm, 0.6mm )

Pre-Processing:-

Geometry:-

Material Selection:-

Structural Steel for wall

Stainless steel NL for car body

Symmetry:-

Meshing:-

Patch Confirming Method:-

All triangles Method:-

Face sizing:-

Mesh:-

Analysis settings:-

Fixed support:-

Displacement:-

Solver Output:-

Case 1:- Body thickness is 0.3mm

Total Deformation:-

Equivalent Stress:-

Case 2:- Body thickness is 0.5mm

Total Deformation:-

Equivalent Stress:-

Case 3:- Body thickness is 0.6mm

Total Deformation:-

Equivalent Stress:-

Results:-

Conclusion:-

The increcases in thickness results decrease in ductile nature followed by increase in hardness of body.
With increase in thickness value the total deformation decreases slightly.
Same as with Equivalent Stress increase in thickness results in decrease in stress values.
