OSTI ID:6781008
A method to determine the strain history throughout a body by integration of the deformation rates or deformation gradients in an Eulerian reference frame is presented. With knowledge of the strain history, a viscoplastic formulation is extended to include strain history dependence. The extended viscoplastic formulation and strain history integration are applied to the thermomechanical analyses of slab rolling and axisymmetric extrusion.
