Objectives
Knowledge to be acquired in this module covers introduction in the fundamentals of material science and strength calculation to understand the formation of critical loading situation in key components in (power) plants and thus the damage mechanism oriented failure. At the end of the course students are expected to be in the position to evaluate possible damage scenarios in components on basis of general information such as operation data, material and macroscopic and microscopic damage appearance.
Target Attendees / Participants
University students of Steinbeis European Master Program in Risk Engineering and Management, and similar programs.
Course Content by Units
Structure of metals and basic material behavior
Introduction into basic damage mechanisms
