Dynamic models of material in metal forming
 Kudláčová, Barbora ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The aim of the Diploma Thesis is to discuss the creation of material models for the forming technology in quasi-static and dynamic loading conditions and to practically propose a methodology of modeling the mechanical behavior of the selected material for dynamic load conditions using the Split Hopkinson Tensile Bar Test. The presented work contains an overview and analysis of individual experimental methods with the influence of the strain rate in terms of the extent of their suitability, the analysis of the plastic deformation mechanism, an overview of the mathematical mechanical behavior models for the materials used for technological practice and the evaluation of the mechanical behavior of stainless steel according to ČSN 41 7348 in terms of flat formability incl. evaluation of microstructure, fractographic analysis and evaluation of results from ferromagnetism measurement of steel after dynamic loading.
