Course content

Phenomenology and physical mechanisms, plasticity (yield criteria, flow laws, hardening rules), viscoplasticity, thermo(visco)plasticty, plastic anisotropy, damage mechanics, large deformations, crystal plasticity, integration algorithms.

Learning outcome

The candidates should have knowledge and understanding of the theory of plasticity for large deformations and the theory's applications in non-linear analysis of structures.Knowledge:The candidates will understand the various theoretical elements of plasticity and the established plasticity models for metallic materials.Skills:The candidates will be able to derive and apply equations in the theory of plasticity for large deformations and apply established plasticity models in the analysis of structures. They will also be able to identify material parameters from laboratory experiments, and be able to implement plasticity models in the finite element method for nonlinear analysis of structures.General competences:The candidates will understand the main principles of the theory of plasticity for large deformations and be able to use the theory in nonlinear analysis of structures. They will also learn to read scientific papers and to carry out literature searches, and thus be able to form an impression of where the research frontier is in the field.

Learning methods and activities

Lectures, study groups and project work. The teaching will be in English when students who do not speak Norwegian follow the course.
