Abstract : Several aspects of elastic-plastic analysis relevant to technological applications which have been investigated on the project are discussed. References to the reports or papers dealing with these aspects are given. The topics are: (1) the generation of residual stress in metal-forming processes, in particular extrusion; (2) finite-deformation elastic-plastic theory based on the nonlinear coupled kinematics; (3) stress analysis in the presence of anisotropic hardening, in particular kinematic hardening; and (4) computer program development to improve accuracy and generality.
