Course objectives:
|
The tutorial deals with the theoretical fundamentals of stress and force computation in metal forming technology. The students are acquainted with principles and laws of plastic strain mechanics. The state of stress, mathematic relations for small strain computation, the compatibility equations and plasticity conditions are analyzed. Equilibrium differential equations for forming processes are derived and the methods of strain force and power determination are specified. In the user-oriented part, the stress conditions and forces are calculated for upsetting, rolling, wire, and tube drawing using equilibrium equations and the plasticity condition formula. The slip line method is interpreted and several selected tasks are calculated by this method.
