Can anyone assist me with Von mises stress field ambiguity in Abaqus XFEM crack modelling?

I am trying to model an edge crack in an Aluminium plate with thickness (400*400*200) on ABAQUS using XFEM. The crack opens fine (with a little ambiguity in the opening shape), however the Von...

How to make an edge crack open in a 2D model in Abaqus?

I'm modelling an RVE with an edge crack in ABAQUS to study crack propagation using the XFEM method. For some reason the crack is not opening, no matter what load or crack size I use. Could someone...
