Ortega Novillo, Adrián (Date of defense: 2017-04-20)
When a fibre-reinforced composite laminate is subjected to traction or compression, it develops a relatively large Fracture Process Zone where material toughening mechanisms such as matrix cracking, ...
Abdel Monsef, Said Ahmed Ibrahim (Date of defense: 2020-07-02)
Cohesive zone models are widely used for modelling delamination and bonded joints under different loading conditions. In the current thesis, an objective inverse method has been developed to extract the cohesive law from ...
Llobet Vallejo, Jordi (Date of defense: 2020-01-17)
This thesis investigates the fatigue behaviour of fibre-reinforced composite laminates. Fatigue of composite materials is a complex subject both from an experimental and numerical modelling point of view. In this context, ...
