Course Aim
The student should be able to describe
- what physical processes that cause plastic deformations, particularly dislocation- slip,
- what diffusion processes that cause creep of materials,
- and how phase changes cause deformations and the reverse effect.
The student should be able to formulate the theory of plasticity and give examples of models for viscoplasticity and creep.
The student should be able to formulate a plasticity model based on dislocation density and determine its parameters.
The student should be able to explain a algorithm that is used by finite element programs for stress computations and be able to do simpler modifications of the algorithm.

The different steps in material modelling are introduced. Thereafter the physical phenomena that cause plastic deformations and the theory of plasticity for deviatoric plasticity are described. Furthermore, common empirical material models and physical based material models for plasticity are outlined. The method that is used by finite element codes to solve these equations is described.

The course consists of lectures where the theory is given and homework assignments together with one larger assignment where material parameters are determined.

The completed homework should be submitted in short, written form. A complete report for the parameter assignment should be submitted. The form and quality of this report is also part of the examination.
