1. Elastoplasticity of Grey Cast Iron FE-Algorithms and Biaxial Experiments
Sammanfattning : This thesis focuses on multiaxial elastoplastic behaviour of graphitic grey cast iron with the aim to provide physically appropriate and numerically reliable constitutive relations for use in FE-codes. To achieve this goal, this work is divided into three parts: Biaxial experiments are performed on thin cruciform specimens. LÄS MER
2. 3-D Forming of Paper Materials
Sammanfattning : Paper materials have a long history of use as a packaging material, although traditional paper-based packaging is limited in its shape, complexity, and design. In order to better understand the deformation and failure mechanisms during 3-D forming, two experimental studies of paper materials have been conducted. LÄS MER
3. Natural science specialising in physics
Sammanfattning : A new class of liquid crystal materials has been recently discovered. These mate- rials are constituting of bent core (BC) molecules. LÄS MER
4. Modeling and experimental characterization of pearlitic rail steels subjected to large biaxial strains
Sammanfattning : Large shear strains develop in the near-surface region under the running band of railway rails. Rolling Contact Fatigue (RCF) cracks often initiate in this region, causing major problems for the railway industry. However, characterization of the constitutive and fatigue behavior of this region is difficult due to the large gradient of properties. LÄS MER
5. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel
Sammanfattning : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. LÄS MER
