How to measure micro-cracks in plates when the sample is unloaded and the crack surfaces are in contact?

I would like to measure the crack size of plates (i.e., CT under fatigue loading) once I remove them from the testing equipment (they are unloaded). In my case, the crack is very small (the crack...

How to check if the assigned behaviour of a material (Abaqus) is right?

I am modeling 3D CT specimen on Abaqus. The assigned material is elastic-plastic and damage is defined by separation laws. I tried to check in the results if the elements behaviour is the one I...

What is a optimal value for error in residuals for cyclic direct analysis in Abaqus?

As one can see from Abaqus Manual (http://130.149.89.49:2080/v6.7/books/usb/default.htm?startat=pt03ch07s02abo09.html#usb-anl-aconvergeintro), the default residual error for the increment...

Is it possible to model XFEM elements on Abaqus without using damage initiation/evolution for traction separation laws?

I am modeling in Abaqus a metal plate subjected to tension (CT), with an existing crack surface, using XFEM technique. I need to perform cyclic analysis so I need to assign hysteretic response to...
