Prediction of Inelastic Behavior of Composite Laminates Using Multi-Surface Continuum Damage-Plasticity
The recently performed investigations in continuum plastic-damage analysis of composite laminates by the authors showed that using a single hardening internal variable for damage and plasticity surfaces may prone to significant errors in response and failure load for some lay-ups. In this paper, the new technique of coupled continuum plastic-damage mechanics including multisurface dissipation potentials are employed to improve the results. The response and failure loads of the laminated composites with different lay-ups are predicted using elastic, damage, and damageplasticity conditions with single and multi surface plasticity and compared with the available experimental results.
