ABAQUS XFEM crack propagation

Load Displacement curve for XFEM in ABAQUS

I am using Maxps Damage criteria for an XFEM crack for a three point bending case. I am using displacement loading on the specimen and wish to plot reaction load v/s mouth opening displacement. I would like to know how to obtain the crack tip opening displacement in ABAQUS. All the journal papers I read show a slump in reaction force after the crack starts to propagate. I plot the results and contour plots show me clearly that the crack has started to propagate. Please help.

Modelling Crack in Abaqus

Hi everyone

I am new user in Abaqus, i read most of the posts related to the modelling the crack but unfortunately i didnt get a clear procedure, maybe it is due to my weakness in this software.

i want to model a crack in abaqus and analysis the crack propagation, actually i am working on piezoelectric material, but i want to know,  can you tell me different steps to model a crack and then how to analyze the propagation on it.

Please help me is this case.  

How to model interfacial crack propagation in ABAQUS with XFEM?

Hello every one.

Just as the topic mentioned above, I wish to know how to medel interfacial crack propagation in ABAQUS with XFEM method. I have already know the "debond" method. I wonder whether the XFEM can solve the interfacial crack propagation ptoblem.

Thank you.
