An optimization algorithm for preform die shape design in metal-forming processes is developed in this paper. The preform die shapes are represented by cubic B-spline curves. The control points of the B-spline are used as the design variables. The optimization objective is to reduce the di erence be

We suggest a shape optimization method for a non-linear and non-steady-state metal forming problem. It consists in optimizing the initial shape of the part as well as the shape of the preform tool during a two-step forging operation, for which the shape of the second operation is known. Shapes are d
This paper is the second part of a two-part article about shape optimization of metal forming processes. This part is focused on numerical applications of the optimization method which has been described in the first paper. The main feature of this work is the analytical calculations of the derivati
In complex forging processes, it is essential to "nd the optimal deformation path and the optimal preform shape that will lead to the desired "nal shape and service properties. A sensitivity analysis and optimization for preform billet shape in thermo-mechanical coupled simulation is developed in th
This paper develops a numerical technique for determining the shape sensitivity parameters in steady metalforming processes such as drawing and rolling. The adjoint method is applied to the discrete non-linear system of equations in the finite element model in order to determine the discrete matrix
