Hello,
I am modelling a crushing simulation of a composite corrugated coupon using Abaqus/Explicit and CZONE Abaqus' application.
I am modeling the coupon using S4R elements and the impactor as a discrete rigid shell plate with a slow constant crushing speed or high initial velocity for quasi-static and dynamic crushing simulations respectively.
I am using Hashin damage in Abaqus/Explicit and Hashin and also Tsai-Wu on CZONE 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.
