COMPUTATIONAL INELASTICITYFHLN05
Credits: 7,5. Grading scale: TH. Cycle: A (Second Cycle). Main field: Technology. Language of instruction: The course might be given in English. Optional for: F4, F4bem, M4bem, Pi4, Pi4bs, V5ko. Course coordinator: Professor Matti Ristinmaa, Matti.Ristinmaa@solid.lth.se, Solid Mechanics. Prerequisites: FHL064/FHLF01 Finite Element Method or VSMN30 The Finite Element Method - Structural Analysis. Assessment: The course is given in seminar form and treats modern aspects of constitutive modelling. Two project assignments should be solved in the course. Examination is based on the two project assignments. The projects consider materially non-linear problems, containing both a theoretical and a numerical part, which are used to solve a practical problem. The three parts will then provide a final grade.

Aim
The course provides an understanding of the mathematical description of non-linear material behaviour. The student will be provided with the mathematical tools necessary for establishing material models as well as the numerical background necessary for the numerical implementation.

Contents
In the course, non-linear material models are considered, as well as the numerical issues when the models are implemented into a non-linear finite element program.

In the course the following subjects are considered:

The projects, in which non linear material problems are considered, consist of an analytical part and a numerical part. In the numerical part the material model is implemented. The program is then used for describing the response of a structure.
