The documentation of the vumat interface has been badly understood in plane stress. The conventions about tensors has not been transcribed appropriately (there have been a confusion with the Abaqus/Standard conventions).
The Native finite strain strategy in Abaqus/Explicit (based on a
corotational formulation) is not supported in MTest, so there is no
unit-tests associated.
