Abstract: his doctoral thesis aims at developing and implementing a computational framework for performing virtual testing of composite structures using a High-Performance Computing (HPC) environment. In this sense, this thesis presents several novel constitutive models based on the continuum damage mechanics theory and their implementation in the HPC-base Finite Element (FE) simulation code called Alya. The verification and validation of the models are performed comparing the numerical predictions with analytical formulations and experimental data. The comparisons demonstrate not only the reliability of the damage models but also the potential of an HPC-based environment for Virtual Testing of COmposite STructures. Therefore, the outcome of this thesis is both the formulation of new fracture models and the numerical framework named Alya-VITECOST
