چکیده:

in this paper, the main features involved in a finite element formulation of the incremental analysis of large deformation and rotation will be described. First the polar decomposition of the deformation gradient is emphasized. Then the way in which the theory is incorporated in a finite element program is discussed. this program concerns the displacement controlled analysis of static instability and subsequent flow of an elasto-plastic solid.
