1. Numerical simulation of weldment creep response
Abstract : In-service inspections of high temperature pressureequipment show that weldments are prone to creep and fatiguedamage. It is not uncommon that severely damaged weldments arefound even before the design life of the component has beenreached. READ MORE

2. Realistic Package Opening Simulations : An Experimental Mechanics and Physics Based Approach
Abstract : A finite element modeling strategy targeting package opening simulations is the final goal with this work. The developed simulation model will be used to proactively predict the opening compatibility early in the development process of a new opening device and/or a new packaging material. READ MORE

3. Robust Preconditioners Based on the Finite Element Framework
Abstract : Robust preconditioners on block-triangular and block-factorized form for three types of linear systems of two-by-two block form are studied in this thesis. The first type of linear systems, which are dense, arise from a boundary element type of discretization of crack propagation problems. READ MORE

4. Simulation of mechanical cutting
Abstract : This thesis deals with simulation of mechanical cutting. It focuses on orthogonal cutting. Thus it is possible to use two-dimensional models. The strong thermo-mechanical coupling must be accounted for in the model. READ MORE

5. Modelling the viscoplastic properties of carbon black filled rubber : A finite strain material model suitable for Finite Element Analysis
Abstract : An increased environmental awareness, legal demands and the large part of total costs attributable to fuel cost are all incentives for the automotive industry to reduce fuel consumption. The optimal driveline to enable this reduction depends on the operational conditions and the available infrastructure. READ MORE
