Hello everybody,
i am trying to calculate the gradient of the hydrostatic stress within the UMATH routine and i obtained the hydrostatic stresses in the integration points from the Subroutine USDFLD. How is it possible to calculate the hydrostatic stress gradients with abaqus similar to these works ?
