Integrity of Structures

Preparatory course Integrity of Structures

Students admitted to the Master Course „DDM“ have a different background in the field of Strength of Materials, which is a key subject in the Master Program. The preparatory course is designed for students who have an insufficient background in this field, who had their Strength of Material Classes a few years ago, who want to refresh their specific knowledge or who want to improve their technical terminology in this subject.

What does the preparatory course provide?

The basics of Strength of Materials with a scope of bachelor courses of roughly 6 credits, which are assumed as prerequisite for the class Integrity of Structures, are repeated and refreshed. The course consists of 6 chapters (Safety of Structures, Fundamentals of Strength of Materials, Design Concepts for Static Loading, Fundamentals of Fatigue, Design Concepts for Fatigue Loading, Fatigue Assessment for Constant Amplitude Loading).

The course explains the theoretical background, practical applications and experimental techniques. The practical application of the theory is deepened in a consistent practical example for each chapter. Homework problems are provided for independent study for each chapter.

When and where does the preparatory course take place?

The course with a scope of 25 hours is offered once a year at the beginning of the winter semester. It usually takes place during the first two weeks of the winter semester at the Esslingen city campus.
