6. A Linearized Euler Method for Unsteady Flow in Axial-Flow Turbomachines
Sammanfattning : A linear Euler method for analysing unsteady inviscid compressible quasi three- dimensional flows in oscillating cascades is developed. It is applicable to both blade flutter and forced response problems. LÄS MER
7. Procedures in Adaptive Finite Element Analysis
Sammanfattning : 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.

8. Efficient finite element modelling and simulation of welding
Sammanfattning : This thesis presents development of methods, methodologies and tools for efficient finite element modelling and simulation of welding. A novel 8- to 16-noded solid shell element has been developed. It uses only displacement degrees of freedom, thus it can easily be connected with a regular brick element. LÄS MER
9. On dynamic crack growth in discontinuous materials
Sammanfattning : In this thesis work numerical procedures are developed for modeling dynamic fracture of discontinuous materials, primarily materials composed of a load-bearing network. The models are based on the Newtonian equations of motion, and does not require neither stiffness matrices nor remeshing as cracks form and grow. LÄS MER
10. Hybrid Grid Generation for Viscous Flow Computations Around Complex Geometries
Sammanfattning : A set of algorithms building a program package for the generation of twoandthree-dimensional unstructured/hybrid grids around complex geometrieshas been developed. The unstructured part of the grid generator is based on the advancing frontalgorithm. LÄS MER
