1. Elastic-Plastic Fracture Mechanics and RCF in Rails
Sammanfattning : This thesis concerns issues regarding the modeling and numerical simulation of singularcracks and their propagation in the context of Rolling Contact Fatigue (RCF) in rails.Typically, such cracks are associated with squats and head-checks in the rail head. LÄS MER
2. Elastic-plastic fracture mechanics - Application to rolling contact fatigue in rails
Sammanfattning : Railway structures represent complex mechanical problems involving wave propagation, plastic deformations and material degradation. The wheel-rail contact loads subject the material to repeated cycles of complex stress states resulting in rolling contact fatigue (RCF). LÄS MER
3. Numerical models of ductile crack growth
Sammanfattning : .... LÄS MER
4. On the crack driving force in elastic-plastic fracture mechanics with application to rolling contact fatigue in rails
Sammanfattning : .... LÄS MER
5. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites
Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER
