Learning outcomes
|
The purpose of the course is to teach the students to understand the load response in more complex cases, to determine stresses and deformations in components in elastic and elastic-plastic state, and to evaluate the safety of a component or to propose the cross-section dimensions for given load and demanded degree of safety or time of operation.
On the course Mechanics of materials II completion, student is able to calculate stresses and deformations in more complex cases (plates, membranes and shells, beams on elastic foundations, elastic-plastic deformations, fracture, fatigue). He/she is able to evaluate the safety of a component or to propose the cross-section dimensions for given load and demanded degree of safety.
