FINITE ELEMENT METHOD FOR NON-LINEAR SYSTEMSFHL066
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, F4bs, M4bem, M4fo, 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 consists of a series of seminars. In parallel computer laborations the numerical implementation is given. Examination is based on the two project assignments, which consider both theoretical and numerical issues. The projects are graded and the final grade is based on the total grade. Home page: http://www.solid.lth.se.

Aim
The aim of the course is to provide an understanding about modelling and simulation of non-linear structural and material problems using the finite element method.

Contents
The course treats the finite element method where both geometrical and material nonlinearities are present. The fundamental equations for large deformations and strains and the various strain measures and stress measures are introduced. The corresponding strong and weak forms of the equilibrium equations are discussed, both in their spatial and material format. The nonlinear finite element formulation is derived from the general three-dimensional case. Emphasis is given to the fundamental principles in the FE-formulation. During the course, the participants are going to establish their own nonlinear FE-program.
