1. Computational weld mechanics : Towards simplified and cost effective FE simulations
Sammanfattning : It is the demand of the world’s ever increasing energy crisis to reduce fuel consumption wherever possible. One way of meeting this demand is by reducing the weight of a structure by replacing thick plates of low strength steel with thin plates of high strength steel in the structure. LÄS MER
2. Numerical Model Reduction and Error Control for Computational Homogenization of Transient Problems
Sammanfattning : Multiscale modeling is a class of methods useful for numerical simulation of mechanics, in particular, when the microstructure of a material is of importance. The main advantage is the ability to capture the overall response, and, at the same time, account for processes and structures on the underlying fine scales. LÄS MER
3. Computational methods for assessing chemical risk : focusing on toxicokinetic modelling in zebrafish (danio rerio)
Sammanfattning : New chemicals are constantly produced and large data gaps exist on hazards of currently used industrial chemicals, stressing the need for rapid, ethically sound and cost-efficient hazard assessment methods. Traditional methods for effect assessment based on animal testing, do not meet these requirements and thus the toxicology field has been moving towards the development of new approach methodologies which include in vitro approaches but also computational methods.

4. On Error-Controlled Numerical Model Reduction for Linear Transient FE² Analysis
Sammanfattning : Multiscale modeling is of high interest in the engineering community due to its ability to capture the overall response, while still accounting for processes and structures on underlying fine scales. One standard approach to multiscale modeling is the so-called FE² procedure, where the classic constitutive relation is replaced by a boundary value problem on a Representative Volume Element (RVE) comprising the underlying microscale features.

5. Computational Modeling, Parameterization, and Evaluation of the Spread of Diseases
Sammanfattning : Computer simulations play a vital role in the modeling of infectious diseases. Different modeling regimes fit specific purposes, from ordinary differential equations to probabilistic formulations. LÄS MER
