Abstract

In this paper, a new criterion is proposed in order to determine the necessity of preform steps for axisymmetric H-shaped parts in multi-stage hot forging based on shape complexity factor. The proposed geometrical based criterion was implemented in several examples using finite element method and experimental tests to verify the presented criterion. Finally, in comparison with the existing criteria, results show that the proposed criterion is in excellent agreement with experimental results in order to estimate the optimum number of preform steps.
