Springback compensation method for doubly curved plate in multi-point forming

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.
