1. Analysis of transverse composite cross-ply laminates
Sammanfattning : Advanced polymer composites are commonly based on thin prepreg plies stacked at different angles to form a laminate. When the laminate is loaded, intralaminar transverse cracking in off-axis plies is one of the first damage modes. In the presented thesis, cross-ply laminates are used to study the transverse cracking phenomenon. LÄS MER
2. Analysis of transverse cracking in cross-ply laminates: Weibull distribution based approach
Sammanfattning : Fiber reinforced polymer composite laminates make up more than 50% of modern aircrafts. Such composite laminates are exposed to various environmental and in-service thermo-mechanical load conditions. LÄS MER
3. Transverse cracking in cross-ply composites during static and fatigue loading at different temperatures
Sammanfattning : Polymer composite laminates are preferred in many load bearing applications for its tailorable mechanical properties while offering light-weight solution, corrosive resistance etc. Hence, polymer composites are attractive material choice for aircraft manufacturers to reduce weight and emissions.

4. Damage accumulation and stiffness degradation in composite laminates
Sammanfattning : In the presented thesis analytical modeling of elastic properties degradation and modeling of damage evolution in composite laminates is performed. Transverse cracking initiation on a fiber/matrix level is briefly studied by testing model composites and cross-ply laminates. LÄS MER
5. Degradation of thermo-elastic properties in damaged composite laminates : a theoretical study
Sammanfattning : Fiber composites are today widely used in different load carrying structures. The main reason is their high stiffness and strength to weight ratio. Due to these specific properties they are frequently used in car, marine and space industry. LÄS MER
