Why does the Abaqus simple tension simulation fail to converge for 2 elements perpendicular to load but not for 2 elements parallel to load?

I am simulating a simple uniaxial tension by pulling for a displacement of 0.4 in the Z-direction on a quarter symmetry cube with side lengths of 0.8. I am using an elastoplastic self-consistent...

How to better control the sharp notch for an Abaqus Umat simulation?

I have a notched specimen as shown in attached NotchedSpecimen.png. It is basically a bar with 4 circular cuts on four sides. As a result, the specimen has 4 sharp notched edges. It is a quarter...

Weird bug with Abaqus boundary conditions?

I made a model and meshed it with quadratic tet and applied symmetry boundaries on the three flat surfaces. The model is pulled in tension by applying z-displacement on the back surface (not...
