Recent improvements in manufacturing processes and material properties associated with excellent mechanical properties and low weight make them very attractive composite materials for use in aerospace structures. Several criteria and failure theories have been developed to describe the process of damage and its evolution, but the solution of the problem is still open. This work presents the development of a delamination model and its application to simulate the progressive failure of structures made of composite material. The model of delamination to be developed will be implemented as subroutines in FORTRAN (UMAT-User Subroutine and UEL Material - User Element Subroutine), to be compiled by the commercial program of Finite Elements ABAQUSTM. Model validation is performed by comparing the numerical results with experimental results. Parallel to the development of delamination model, a new formulation for laminated shell finite elements based on the generalized finite element method in order to improve the results of the numerical simulations where localization and large stress gradients are a major issue when performing progressive failure analysis. The finite element formulation is then verified by traditional numerical experiments. Finally, once validated the finite element formulation, the model material contemplating the process of intralaminar and interlaminar failure will be tested together with the generalized finite element formulation to simulate composite structural failure analysis.
