New Strategies in Finite Element Analysis of Material Processing

Under the supervision of Professor Bernd-Arno Behrens, the head of the Institute of Metal Forming and Metal-Forming Machines (IFUM), three PhD projects were carried out during the span of the Research Training Group 615 (GRK 615). All the projects originated in the Department of Numerical Methods, which is headed by Dr. Anas Bouguecha, and were related to finite element modeling and simulation of materials processing. Thus, Kanwar Bir Sidhu developed and implemented remeshing and rezoning algorithms to cope with severe plastic deformation and crack propagation in thin sheet blanking. The subject of Ilya Peshekhodov was a multiscale approach in modeling of forming processes of metal sheets coated with thin polymer composite coatings. With the help of the fluid mechanics approach, Thorsten Matthias modeled bulk forming processes of aluminum alloys in a semi-solid state. These projects are presented below along with some exemplary results.
