Hi everyone,
For current project at work I am looking into possibility of simulating deformation from impact with static force.
Here is the input data:
A ball of 0.5 kg at speed of 25 km/h crashes into a damping foam which is placed on a rigid wall. Stopping (deformation) distance in the foam is 35 mm and deceleration is 70G (see picture)
I calculate impact force as F=m*a=0.5*70*G=343,35 N
The question is, if I put the same foam horizontally on a floor and will press in the ball (i.e. pressing area will be the same) with equal static force of 343,35 N (which will mean 35 kg load), will the deformation in the foam be the same 35 mm?
