| Sumario: | 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, we designed a quite extensive experimental campaign to investigate the failure mechanisms that occur when the composite material undergoes fatigue. Then, we developed a constitutive model to anticipate the mechanical behaviour and the final strength of the material. This model was implemented inside a finite element code in order to analyse the behaviour of composite structures under different loading scenarios. The final objective of this type of numerical tool is to reduce the number of test and time required for certification of aerospace composite parts |
