Course content

Stresses and strains. Elasticity and thermoelasticity. Anisotropy and symmetry planes. Linear viscoelasticity. Plasticity and viscoplasticity (yield criteria, flow law, hardening, effects of strain rate and temperature). Finite element method for nonlinear materials.

Learning outcome

The course will give the theoretical basis to establish material models for elastic, viscoelastic, plastic and viscoplastic materials. The students will be able to carry out analytical calculations for simple structural elements with nonlinear material behaviour and to conduct finite element analyses of structures with material nonlinearity.

Learning methods and activities

Lectures and compulsory exercises. 2/3 of the exercises must be approved to get access to the exam. If there is a re-sit examination, the examination form may be changed from written to oral. The lectures and exercises are in English when students who do not speak Norwegian take the course. If the teaching is given in English the Examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
