Résumé

In this paper, the plane stress version of the Puck's failure theory is used as an indicator of the intra-laminar meso-damage initiation. The thermodynamically consistent damage evolution law is defined to accumulate the damage leading to the subsequent stiffness degradation coupled with the isotropic hardening plasticity. The model is formulated in incremental form keeping in view the implementation by following the plasticity theory which is later used in the Return Mapping Algorithm (RMA). In the implicit scheme based on the Newton-Raphson approach, the consistent tangent operator is derived for the current model. The developed model has been implemented in ABAQUS/Standard via UMAT subroutine in a strain-driven problem where strain tensor is provided as an independent argument into the solution scheme. The non-linear mechanical behavior and ultimate failure of Carbon Fiber Reinforced Polymers (CFRPs) laminates are predicted for the small strain time-independent boundary value problem. The results are compared with the experimental results collected from the previously published literature which exhibit better correspondence.
