About the Course

Course Content

The course covers phenomenology and physical mechanisms, plasticity (yield criteria, flow laws, hardening rules), viscoplasticity, thermo(visco)plasticty, plastic anisotropy, damage mechanics, large deformations, crystal plasticity, and 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. This includes:

• Knowledge of the various theoretical elements of plasticity and the established plasticity models for metallic materials.
• Skills to derive and apply equations in the theory of plasticity for large deformations and apply established plasticity models in the analysis of structures.
• Ability to identify material parameters from laboratory experiments and implement plasticity models in the finite element method for nonlinear analysis of structures.
• General competences to understand the main principles of the theory of plasticity for large deformations and use the theory in nonlinear analysis of structures, as well as the ability to read scientific papers and carry out literature searches.

Learning Methods and Activities

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