Course description
Course content
Dimensional analysis and scaling. Finite difference methods: diffusion equation in 1d and 2d; elastic wave equation in 1d and 2d; fracture. Approximation techniques: trial functions, and Galerkin’s Finite Element Formulation. Finite Element programming in Matlab: program structure; matrix elements and vectors. Laplace’s and poisson’s equations. Elasticity: plane stress; plane strain; three-dimensional solid: dynamics, thermal stress. Viscous, visco-elastic, and visco-elastoplastic rheologies. Coupling of deformation and fluid flow.

Admission
PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.
If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.
PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
