Locking suppression techniques and their application to FEM – analysis of processes of deformation of thin-walled objects

The description of various techniques of elimination of locking phenomenon in the degenerated finite elements, based on the Timoshenko-Mindlin hypotheses, is presented. The use of these techniques is illustrated on the problem of hydrostatical forming of thin metal sheet.
