Tesis doctoral de Albert Turon Travesa
A design tool for the analysis of delamination in laminated composites was developed. The design tool is developed using the damage-tolerance concept to predict both delamination initiation and growth. Therefore, the model developed can be used to perform either strength or damage-tolerance verification of new components, and can be used to assess the necessity to repair or replace in-service components. The model developed can be used either to simulate quasi-static or fatigue loading. a thermodinamically consistent damage model is proposed for the simulation of delamination in composite materials under variable-mode loading. The model is formulated in the context of damage mechanics by means of the cohesive zone model concept. Moreover, a methodology to determine the parameters of the constitutive model is proposed. The methodology presented allows the use of coarser meshes that is usually admissible. Finally, the model has been enhanced to simulate high cycle fatigue.
