Hi, Im Bayu from undergraduate program from University in Indonesia.

I have my thesis is crash performance on the hybrid (AL/GFRP) crashbox.

In the contact between Alumunium shell (Inside) and GFRP shell (Outside), I use the Automatic_Surface_To_Surface_Tiebreak with contact option 2.

I have the problem that my GFRP model can be penetrated by other model and also by other composite model. There is no surface_to_surface contact that are generally applied and make the model cannot penetrate or penetrated each other.

Are there any solve to the problem? [Note: I cannot change contact Option 2 because the value is same with the experimental i use as reference]
