1. Hierarchical finite element modelling of Biot's equations for vibro-acoustic modelling of layered poroelastic media
Abstract : This thesis concerns three-dimensional finite element modelling of Biot's equations for elasto-acoustic modelling of wave propagation in layered media including porous elastic materials. The concept of hierarchical (p-version) finite elements are combined with various weak forms of Biot's equations. READ MORE

3. Procedures in Adaptive Finite Element Analysis
Abstract : The present work is concerned with topics related to some adaptive methods for the approximate solution of differential equations. Emphasis is on the finite element method for second order elliptic equations, where we use either p-refinement or remeshing with an advancing front mesh generator in order to improve approximate solutions.

4. Advancing Front Mesh Generation Techniques with Application to the Finite Element Method
Abstract : The present study deals with automatic mesh generation with application to finite element methods. We focus our interest on unstructured mesh generation, and in particular on advancing front methods for which algorithms for meshing of two and three dimensional domains as well as of free-form surfaces are devised.

5. Adaptive finite element methods for plate bending problems
Abstract : The major theme of the thesis is the development of goal-oriented model adaptive continuous-discontinuous Galerkin (c/dG) finite element methods (FEM), for the numerical solution of the Kirchhoff and Mindlin-Reissner (MR) plate models. Hierarchical modeling for linear elasticity on thin domains (beam-like) in two spatial dimensions is also considered, as a natural extension of the Bernoulli and Timoshenko beam theories. READ MORE
