Abaqus full penetration

Abaqus full penetration

Abaqus full penetration

(OP)
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?

RE: Abaqus full penetration

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.
