hashin

Hello,

I am modelling a crushing simulation of a composite corrugated coupon using Abaqus/Explicit and CZONE Abaqus' application.

Hi Everyone,

I am doing a project in which I am trying to study about the
drilling of composite. The aim is to optimize the drill and process
parameters to minimize the damage. For this I have tried to simulate
the drilling process in ABAQUS and I am using the Hashin damage model.
The problem is that Hashin damage model works only for the lamina which
takes only plane stress elements. Since only plane elements are allowed
I am unable to simulate cutting action of drill as the composite plate
is effectively 2D.
