Course content

This course discusses the basics of mechanics and materials science with the objective of rationalizing, predicting, modifying and describing the mechanical behavior of materials. The focus is on the correlation between structure-property-performance.

The course starts with the relationship between stress 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.

For polymers, the temperature dependence of polymer mechanical properties, and failure mechanisms such as yielding, crazing, creep and stress rupture are presented. The material models for evaluating viscoelastic deformations are introduced and the time-dependent response is evaluated from Kelvin, Maxwell, Zener, and four parameter models. Curve fitting of relaxation stresses is carried out by using Prony series. Boltzmann superposition principle and the time-temperature superposition principle are reviewed. Rubbers with nonlinear elastic stress-extension characteristics are introduced.

Learning outcome

Knowledge:
- Advanced knowledge about micro-macro relationships and theory of plasticity in relation to plastic forming.
- Knowledge about the time and temperature dependent response of polymers, failure mechanisms and rubber elasticity.
- Apply the basic knowledge on the materials groups aluminium, steel, stainless steel, and polymers.

Skills:

- Basic modeling on viscoelasticity, applying the Boltzmann superposition principle,the behaviour of rubbers, and estimation of homogenized properties for particulate and short fibre composites
- Carry out case study 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 on lectures, exercises, and a project work. For project work, a list of possible topics will be provided. However, proposals for interesting course related topics are also welcome. The students work in teams on a selected topic.

Further on evaluation

The outcome of teamwork in the form of two short reports and two presentations will be evaluated, and 30% + 30% = 60% of the final grade will be based on this evaluation. If significant differences in the contributions from group members have been documented, individual adjustment of final grading may be considered.

Portfolio assessment is the basis for the grade in the course. The portfolio includes individual home assignments (max 40%) and compulsory project works in groups (max 60%). The results for the parts are given in %-scores, and the entire portfolio is assigned a Pass/Fail grade from the 65% total result level.

For a re-take of the course, all assessments during the course must be re-taken.
