Sammanfattning : The thesis deals with some fatigue related problems in railway mechanics related to increased axle loads and speeds. The focus is on defects and discontinuities in the wheel--rail system that affect the risk of fatigue and fracture of railway components such as wheels, rails and insulated joints. LÄS MER
Sammanfattning : The thesis deals with fatigue related issues in the field of railway mechanics. In particular rail breaks and deterioration of insulating joints are investigated. The study is largely motivated by plans to increase allowed axle loads in Sweden. LÄS MER
Sammanfattning : In this thesis, user friendly and efficient methods for the design of glass structures are developed. The glass structures comprise various boundary conditions. Several types of glass are considered: single layered glass as well as laminated and insulated glass units. Typical load cases for strength design of glass are applied. LÄS MER
Sammanfattning : This thesis is focused on mechanical loads and moisture related problems with a potential to critically harm the functionality of pre-insulated district heating pipes and pipe joints. Directly buried pipeline bends are investigated with respect to limiting deformations from a thermally induced lateral displacement. LÄS MER
Sammanfattning : Mass impregnated paper insulated cables in distributionnetworks (6-33 kV) nowadays are gradually being replaced byXLPE insulated cables, yet, the percentage of mass impregnatedcables in distribution networks is still considerable. Thisreplacement is a long-term strategy, where right timing,properly made investments, etc. play crucial role. LÄS MER
