Subject aims expressed by acquired skills and competences
To give students of Applied Mechanics with different experimental methods designed to analyze the deformation (stress) behavior of materials, which is induced in components of external loads or residual stress from the technological processes of manufacture, etc. Students learn the application of selected methods to specific examples.
