15 صفحه اولShape optimization and preform design in metal forming processes
A continuum sensitivity analysis is presented for the computation of the shape sensitivity of ®nite hyperelastic±viscoplastic deformations involving contact with friction using a direct dierentiation method. Weak shape sensitivity equations are developed that are consistent with the kinematic analysis, constitutive sub-problem as well as the analysis of the contact/friction sub-problem used in...
متن کاملOptimization of Preform in Close Die Forging by Combination Of Neural Network and Genetic Algorithm
In this essay, a combination of neural network and genetic algorithm has been studied for optimization of the preform in close die forging. Finite Volume Method (FVM) is used as a simulation tool for forging processes. The simulation results have used in the neural network and the genetic algorithm has been employed to optimize the forging force. The neural network was used in three stages for ...
