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.
When I take 3D elements then Abaqus shows error that Hashin damage
model cannot be applied for that plate. Also there is no other damage
model for composites in Abaqus.
As a result, I am stuck in this project. Please suggest.
Thanks
