Aim
The aim of the course is to give detailed theoretical and practical knowledge on the finite element method to be able to model and analyse general problems described from a physical context. The finite element method is utilised for solving common problems within the field of engineering, such as, heat flow, ground water flow, diffusion, 2- and 3-dimensional elasticity problems, beams and plates.

Contents
The course consists of lectures, exercise sessions and three compulsory design assignments. In the first part of the course a detailed derivation of all the steps in the finite element formulation are given for a one-dimensional heat flow problem: direct approach, strong and weak formulations, approximating functions and weighted residual methods. More advanced problems are gradually added to this basic knowledge, such as, field problems and solid mechanics problems. Field problems that are studied: heat flow, groundwater flow and Saint Venant torsion. Solid mechanics problems that are studied: stresses and strains, 2 and 3D elasticity, beams and plates. At the end of the course the theory for isoparametric finite elements and numerical integration is introduced. The design assignments illustrate the procedure of transferring a design problem into a model suitable for finite element analysis.
