Abstract
A method is proposed for calculating the fatigue life of dies used in hot stamping. Failure is assessed in terms of the strain and kinematic factors. Thermocyclic weakening is taken into account in determining the accumulated plastic strain. A special subprogram permits prediction of the number of cycles to die failure on the basis of finite-element modeling of tool–blank deformation.
