Hello guys,
I am working on an UMAT subroutine (ABAQUS) for the mechanical behavior of solid materials. I test the subroutine on 1 cubic element. All simulation is done in a condition that the pressure is applied on the surfaces so theoretically, all shear components are 0 (S12=S13=S23=0)...
Hi guys,
I am trying to implement an UMAT subroutine into ABAQUS.
It is a very simple non-linear elastic model, in which the Young's modulus depends on the mean pressure, in details, E=3*(1-2*poisson)*p/kap (where, p is mean pressure, poisson=0.3 is Poisson's coefficient and kap=0.005 is...
