6. 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
7. Modelling of cyclic and viscous behaviour of thermomechanically loaded pearlitic steels; Application to tread braked railway wheels
Sammanfattning : In service, railway wheel and rail materials are subjected to high stresses and, in some cases, elevated temperatures. The high stresses are caused by the rolling contact between wheel and rail. Furthermore, heat generated from tread braking and/or sliding between wheel and rail gives additional stress due to constrained thermal expansion. LÄS MER
8. Patellar tendinopathy : on evaluation methods and rehabilitation techniques
Sammanfattning : Background: Patellar tendinopathy is an increasingly common overuse and degenerative injury for recreational and elite athletes. The management of this injury is often difficult and frustrating and the treatment may take a long time. LÄS MER
9. A study of the rail degradation process to predict rail breaks
Sammanfattning : Rail infrastructure is a large and costly investment, and has a long life. To realize the benefits from this investment, effective maintenance is required. LÄS MER
