21. Relaxation and nanomechanical studies of the vickers residual stress field in glass
Sammanfattning : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. LÄS MER
22. Residual stresses, fatigue and deformation in cast iron
Sammanfattning : The complex geometry of cylinder heads in heavy-duty diesel engines makes grey iron or compact graphite iron a preferred material choice due to its price, castability, thermal conductivity and damping capacity. Today’s strict emission laws have increased the demands on engine performance and engine efficiency. LÄS MER
23. Residual stresses and shape distortion in composite structures
Sammanfattning : High performance composites usually consist of continuous fibres and a thermoset matrix. One well-known example from the aerospace industry is carbon fibre epoxy composites. For that reason the manufacturing processes of thermoset composites are subject to extensive research. LÄS MER
24. Comprehensive numerical analysis of stress state in adhesive layer of joint including thermal residual stress and material non-linearity
Sammanfattning : The main objective of this work is to improve understanding of the stress state in the adhesive layer of bonded joints and identify key parameters which govern performance of adhesive joints. This information is crucial for the prediction of the failure initiation and propagation with the further estimation of the durability and strength of adhesively bonded structures. LÄS MER
25. Residual Stresses and Fatigue of Shot Peened Cast Iron
Sammanfattning : The complex geometry of cylinder head in heavy-duty diesel engine makes grey cast iron or compact graphite iron a perfect material choice due to its castability, thermal conductivity and damping capacity. To increase the efficiency of the engine, the fatigue property of the material needs to be improved. LÄS MER
