collision in mechanical domain

Please login with a confirmed email address before reporting spam

Hi all,

I'm a new user (phd student at ENS) of COMSOL for using in structural mechanics. My problem is to show as a function of the time the deformation (possibly his break) of a cube made in metal launched with an initial velocity (v = 1m/s) on an another material (plate made of metal or plastic). The ideal will be to show the deformation and possibly the break of the cube and of the target (the another material) as a function of the time.

Imagine a small cube launched on a soft wall and which penetrates this wall...After the collision, the cube is deformed and there is a hole in the wall...

It is a non-linear problem that I would like solve by using "Structural Mechanics".

Is it possible to do it with COMSOL ? A similar model is there already ? Have you help/idea to give me ? In my side, I have already solve a part of the problem by using the software LS-DYNA but I would like now use COMSOL.

This problem is important in the aerospacial domain to study the collision between a satellit and a small meteorit...

Thank you

Claire Dupont

Hi Claire,

I am simulation a similar model with yours, have you got any answers about how to show the break process using COMSOL? Thanks.
