Selected topics in the theory of plasticity. Plasticity of materials and methods of determination. Formability in the bulk metal forming, stress state influence on the occurrence of fracture during plastic deformation, deformation history. The methodology for determining the Forming Limit Diagram in bulk metal forming. Formability of materials in upsetting, forging, drawing and extrusion. Formability of materials in sheet metal forming, anisotropy of materials. Simulation test methods for sheet metal formability. Evaluation of sheet metal formability based on mechanical tests. The methodology for determining Keeler-Goodwin's chart, the influence of deformation history on the Forming Limit. Optimization of the forming process due to material deformation criterion. Part of course is conducted through independent study and research work in the field related to the case. Research work includes active monitoring of primary scientific sources, organizing and conducting experiments and statistical analyzes, numerical simulations, possibly paper writing in the area of subjects.
