Abstract

This paper proposed a method for determining the plastic behavior for the metal sheets based on inverse analysis. The identification of the material coefficients is performed with a finite element simulation using a minimization procedure starting from a least squares cost function expressed in terms of the experimental forces and of the numerical ones. In fact, the input data for the automatically identification is: the geometrical model, the mathematical form of the flow curve equation and the force-displacement curve obtained experimentally. The output data represented the parameters which defined the material flow curve.
