LEARNING OUTCOMES

The course provides the theoretical development of the mechanics of solids and structures with sufficient rigor to give students a good foundation for the determination of solutions to a broad class of problems of engineering interest. The primary goal is to formulate models, develope solutions and understand the results. 

TEACHING METHODS

The course consists of theoretical lectures and discussion of case studies.

Detailed lecture notes are available on aulaweb.
