Sometimes when you park your car next to the stadium, a ball may fall on your car, so I simulated it in Abaqus. I do some steps to simulate it
1- I make a model of ball as rigid discrete then I import a model of car as deformable
2- I add the Material of the car as Aluminum
*Density 2.5e-09,
*Elastic 70000., 0.3
*Plastic
250., 0.
300., 0.1
3- I make an assembly of the model
4- I add INTERACTION PROPERTIES
*Friction
0.2,
*Surface Behavior, pressure-overclosure=HARD
5- I create a step
*Dynamic, Explicit
, 0.1
6- I add BOUNDARY CONDITIONS in the model Symmetry/Antisymmetric
Boundary and Predefined Field as Velocity.
7- I make the mesh and create a job
Finally , this is the result
