Abstract
Analytical relations for the calculation of deformations, strains and forces in the process of drawing with reheating of parent sheet of material are proposed. The material on a trial basis is anisotropic, relaxing under visco-plastic defor-mation. Deformations and strains are determined in the flattened portion of the flange and in the bending area of the workpiece on the angular surface of the matrix. Creep flow state equation, equilibrium equation and yield conditions for anisotropic material are used. The kinematics of material damaging has been viewed. The calculated results have been given.
