Course content

This course discusses the basics of mechanics and of materials science with the objective of rationalizing, predicting, modifying and describing the response of materials to stress. The focus is the correlation between structure-property-performance. The course starts with the correlation between stresses and strains in the elastic regime, followed by the theories of plasticity and failure. It concentrates on the physics of deformation and its interaction with the microstructure. The course also considers the different mechanisms of strengthening of metals through grain refining, alloying with interstitial and substitutional solutes, precipitates, second-phase, etc.

Learning outcome

Knowledge:
- Advanced knowledge about micro-macro relationships and theory of plasticity in relation to plastic forming and fracture.
- Knowledge about fracture mechanics and fatigue.
- Apply the basic knowledge on the materials groups aluminium, steel and stainless steel.

Skills:
- Perform FE analysis of plastic deformation in metals.
- Perform fracture mechanics analysis.
- Carry out Case in cooperation with other students and plan, perform and present the results.

General competence:
- General competence in mechanics of materials with an in-depth understanding of the quantitative relationships characterizing the properties of the materials.
- Can cooperate and have a good understanding of cooperative working procedures.

Learning methods and activities

The teaching is based upon lectures, exercises and team work. The students work in teams on three cases, and 40% of the final grade is based on the achievements from these cases. Laboratory exercises are included in the cases. The first case is introduced the first week of the semester, and the students are kindly asked to show up the first week. Assessment for the course is partially based on group projects. If significant differences in the contributions from group members have been documented, individual adjustment of final grading may be considered. If there is a re-sit examination, the examination form may be changed from written to oral.
