Abaqus is a powerful hydro code capable to many things. A large number of publications regarding ballistic events are present, but most authors have used LS-Dyna or AutoDYN. Is it ABAQUS can’t match other codes in this domain?
Not at all. Check out this paper, for example:

Luca Di Stasio I think I couldn’t convey my point earlier. I wanted to know about modelling of composites as homogeneous orthotropic materials with progressive damage.
It's good as well.
There is an entire section (#24) of the Abaqus' User Guide devoted to Progressive Damage and Failure

See some examples here

And if built-in features are not enough, you can always resort to writing a custom UMAT subroutine.
I appreciate the reply. Inbuilt damage model is based on Hashin's theory, but there is only one of it. Also we can us it only for elements with plane stress formulations for 3D cas. I've used it for impact applications. They work well for low velocity impact but not for high velocity as they don't get deleted. There is always an error of excessive deformation of elements.
So as you also suggested, I started writing my own subroutines for 3D continuum elements with element deletion. Challenge there is that, thickness of a layer of ballistic composite is very small, around 250 microns, and to model behavior effectively I need to insert atleast 4 elements through thickness. This increases computation time substantially. There are more issues in contact definitions. My simulation runs but it's doesn't represent experiments.
But my point is it seems from papers there are many material and damage models readily available in LS-Dyna and AutoDyn. Coding everything for ABAQUS seems redundant somehow. It would help if I can see it's not.
There are several literature's available on ballistic impact using Abaqus software. Depending on your model you can write subroutine as well.
