Finite element simulation of sheet metal forming is a well-established tool which is used in industrial practice to evaluate geometrical defects caused by elastic springback. Springback can be defined as an elastically-driven change of shape of the deformed part upon removal of external loads. This phenomenon results in a deviation of the real product geometry from that defined in the design phase and can cause significant problems during assembly. To keep the product development time and manufacturing costs low, finite element analysis aims to provide reliable information necessary for the modification of tool and product geometry. Therefore, the accuracy of information obtained in a numerical simulation of springback is essential for the product designers and die makers. This thesis deals with the improvement of numerical prediction of the springback phenomenon in sheet metal forming. Modelling guidelines and advanced numerical algorithms are presented that better satisfy industrial requirements for an accurate simulation of springback.
