Learning outcomes
|
The aim is to explain the students the principal terms of reliability, and to teach them how to solve problems if the input quantities vary or deviate from nominal values. Thorough explanation of fatigue processes and fatigue endurance, especially under random loading.
The graduant knows the general principles of reliability and is able to solve problems if the input quantities vary or deviate from nominal values. He has got thorough knowledge of fatigue processes and fatigue endurance, especially under random loading
