Abstract


This paper focuses on the progressive failure analysis of a composite at lamina scale using two different material property degradation models in an open hole specimen under uniaxial tension. Puck failure criterion is selected to detect the onset of damage. The ABAQUS user defined material subroutine UMAT was developed to apply the failure criteria and degradation models. A partial discount method and a gradual stiffness degradation is implemented in ABAQUS environment. The damage initiation and progression obtained from the proposed model is compared with the observed experimental results from digital image correlation. The comparative study confirmed that the simulation results were in good agreement with the experimental results.
