报告简介:

To prevent mechanical elements and structures from failing is since ever one of the most important design issue for engineers. For long times, there was no other possibility then try-and-error and experimental methods, accompanied by more or less heuristic analytical estimations. It is only since the beginning of the 20th century that mathematical models and methods have been introduced in order to predict the load limits of mechanical elements.

In modern times, these methods have developed tremendously fast and are nowadays integrate part of any technological development and design. In this lecture, examples of mathematical modeling and numerical simulation of the behavior of mechanical structures will be presented, focusing on the problem of failure due to inelastic effects, mainly plasticity. Case studies from pressure vessels under thermo-mechanical loading and the failure of thermally highly loaded railway brakes will be presented.
