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 (Fecha de defensa: 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 (Fecha de defensa: 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, ...
Delgado Sanglas, Jordi (Fecha de defensa: 2013-06-25)
Selective laser melting process is an additive manufacturing technique that allows obtaining, from a 3D model, a physical model through a layer-by-layer manufacturing strategy. Several machines are commercially available, ...
