Description

A new capability has been developed where sheet metal can be multi-axially strained while stresses in various directions within the plane of the sheet are measured using x-ray diffraction. This system is being used to see how yield loci change with plastic strain level and with changes in multi-axial strain path. Opportunities exist to study structure-property relationships using electron microscopies and x-ray and neutron diffraction and theoretical work on modeling constitutive behavior. Numerous opportunities exist to interact with industrial partners through established, ongoing research collaborations.
