In sheet-metal forming dies, highest stresses occur in bars which connect die to the frame. Considering fatigue behavior of bars with finite element method and probabilistic analyze provide many advantages predicting the life of dies in the design process. An effective and efficient design strategy is proposed to design sheet-metal die in order to reduce stress and increase fatigue life of sheet-metal die. In this strategy, finite element analysis, Approximate model, a numerical optimization algorithm and probabilistic design method Monte Carlo simulation are integrated to create an automated design tool.
