Is it possible to use S4R shell with a vumat to compute stresses in direction 1, 2, 12, 13, 23?

01 January 2015 0 4K Report

We are working on a material model for composites on which we would like to include transverse shear behaviors. Actually in abaqus, even with an isotropic model used with s4r or sc8r shell elements, it is not possible to get S13, S23, even if it is clearly stated in the abaqus documentation that Mindlin thick shell theory can be used.

Any help?

Thanks
