An Inverse Problem of Reinforced Panels Forming

An interesting feature of forming large-size thin-walled constructions is the considerable elastic recovery on their releasing from applied external loads. Because all geometric configurations of parts and external loads during forming are unknown, they can be only determined by solving the problems inversely. The relaxation process, as the most important mode of loading, is considered in this study and the whole process of heat- forming, including elastic recovery, is solved on the basis of the finite element method. Materials in view include Ti and Al alloys.
