Shape optimization and preform design in metal forming processes
The authors perform shape sensitivity analysis for finite deformations of hyperelastic-viscoplastic bodies, taking into account contact with friction. Weak shape sensitivity equations allow to perform kinematic, constitutive and contact-friction analysis. To solve the problem numerically, the authors use the finite element method. The developed algorithms can be applied to the solutions of many practical shape optimal design problems in open-die forging processes.
