"Good sheet has good microstructure".....yeah initial microstructure might be good, but microstructure continuously evolves during plastic deformation.As the microstructure changes during deformation, so does the mechanical properties of the material and hence influences the forming of a sheet...
One cannot ignore the effect of crystallographic texture in sheet forming processes. Crystallographic texture has a significant effect on warping.One should use a UMAT that incorporates crystal plasticity. I am working on this. Probably you can contact me after a couple of months, once I get my...
Hello:
I am planning to develop an UMAT for crystal plasticity to be used in ABAQUS. Can I develop my UMAT in C++ and use with ABAQUS ? I know for the fact that in general FORTRAN UMATs are used with ABAQUS. But I am more comfortable with C++ rather than FORTRAN. Could someone please comment on...
