60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.

Learning outcomes:
After successfully completing this module, students will:
-- be able to distinguish and describe static and dynamic stresses, in particular on real components, by analyzing the stress situation in order to then be able to decide which criteria can be used for safety assessment and dimensioning.
-- describe and characterize multi-axial stress and distortion states by determining the existing load stresses and calculating and graphically representing the principal stresses and principal stress directions in order to subsequently assess the stress state with regard to the strength and safety of the component.
-- be able to select a suitable strength hypothesis by analyzing the material and the stress situation and calculate an equivalent stress in order to be able to draw conclusions about the safety of the component later or to design components with a specified safety level.
-- take into account geometric and material variables influencing the dynamic component strength by reducing the permissible stresses with the help of design factors in order to be able to design real components to withstand stresses.
-- dimension simple components under composite, multi-axial loads for static and dynamic load cases using the appropriate strength hypotheses and taking into account geometric and material variables.
-- be able to examine simple components for possible instabilities by tracing the load case back to the Euler critical load cases in order to obtain a statement about the permissible buckling load.
-- be able to restructure their knowledge from the course “Grundlagen der Bauteildimensionierung” by applying energy methods to solve simple problems in elastomechanics in order to be able to analyze more complex statically indeterminate load situations.
-- be able to formulate questions and give speeches in front of larger groups and justify their decisions in front of groups.
