Rigid projectile impact on sheet metal

Hello everyone,

 

I am trying to do a simulation of a rigid projectile (here a ball...) impact on sheet metal (or other material). I have already done an experimental test with an INSTRON Drop Weight Testers. For information, it is my first crash simulation.

 

The goal is to compare the results between simulation and experimental test. In a further point, it will be to analyse the rupture phenomenon.

 

I have created a ball and a sheet that I have meshed  and done everything about the parameters but... I have got two major errors :

 

  • error in solid property : 226 - 312
  • error in initial penetration in interface : 612

 

I have tried to search some information and correct the mistakes but... still not ok...

 

Someone can help me ? I will really appreciate your advice !

 

Kind regards,

Pegase33
