Inverse analysis of the laser forming process by computational modelling and methods

This paper deals with the development of a computational procedure for the inverse analysis of the laser forming process of three-dimensional metal sheet, characterized by double curvature. The procedure is based on the minimization of a vectorial fitness function, obtained by the comparison of the considered target surface with reference deformed surfaces, represented as sixteen point bicubic patches. An FEM-based computational approach has been adopted to evaluate the reference deformed surfaces for the instruction of the processor.
