Learning Outcomes
Successful completion of the course will lead the students to - understand and apply the state-of-the-art methods for determining the lifetime of engineering components subject to cyclic loading with constant amplitudes as well as to stochastic cyclic loading with variable mean loads and load amplitudes - determine the strength / fatigue life of engineering components (except welded structures) in dependence of the applied loading by means of calculational methods - assess the advantages, calculationa accuracy and the application limits of the tought calcualtional methods - determine the influence of materials, treatments and enviroment on the fatigue strength by means of experiments, calcualtion algorithms and models.
