incompressible material in VUMAT
Hi every body,
I am writing a subroutine code in VUMAT for 3D elements. The material is incompressible, anisotopic hyperelastic. Is it possible to write VUMAT for it?
In addition, the material is reinforced. So I should introduce cylindrical local coordinate system in the model. Is it possible to use local coordinate for the model?
I dont think Abaqus/Explicit can accommodate fully incompressible elements. I dont understand your second question about the coordinate system.
Apparently Abaqus/Explicit allows a fully incompressibile option with 3D tetrahedrons.
