Abaqus full penetration

[es0007]

Hi Everyone,

I am trying to make a full penetration to a composite sample, but the impactor can not go whole through at my modelling.

It rebounds from the sample as seen in figure. I tried different material properties such as with ductile damage properties and elastic-plastic properties.
I still have the same problem, so does anyone know what the problem is?

Is it the material properties or contact and interaction proporties between the impactor and the sample?

What are you running the analysis in? My understanding is that this sort of analysis is best suited to Abaqus/Explicit, particularly if you're trying to model a fast dynamic simluation.

Traditional lagrangian elements undergoing extreme deformation may struggle to solve due to the shape of the deformed elements . Perhaps Eulerian-Lagrangian elements may give you more joy.

You may also need to capture the failure models with progressive damage which causes Abaqus/Explicit to remove elements from the mesh as they fail. Abaqus has a number of relevant example problems in the manual that should be of interest to give you the appropriate material models.
