2D higher-order theories for progressive damage model of composite structures based on Hashin and Puck failure criteria

This paper proposes a high-order 2D finite element model for the progressive damage model of composite structures. The model is based on Carrera Unified Formulation (CUF), which allows to automatically implement different kinematics by using an opportune recursive notation. A Newton-Raphson algorithm and the explicit integration scheme is used to find the converged solution. A single element and an open-hole specimen under tensile and compression loads are investigated using a damage model based on Hashin and Puck failure criteria. The proposed model is compared with literature and ABAQUS continuum shell results.
