主 题：composite pressure vessel low-velocity impact failure theoretical solution progressive damage modeling
摘 要：A theoretical solution is aimed to be developed in this research for predicting the failure in internally pressurized composite pressure vessels exposed to low-velocity *** in-plane and out-of-plane failure modes are taken into account simultaneously and thus all components of the stress and strain fields are *** this purpose,layer-wise theory is employed in a composite cylinder under internal pressure and low-velocity *** stress/strain components are fed into appropriate failure criteria for investigating the occurrence of *** case of experiencing any in-plane failure mode,the evolution of damage is modeled using progressive damage modeling in the context of continuum damage ***,mechanical properties of failed ply are degraded and stress analysis is performed on the updated status of the *** the event of delamination occurrence,the solution is *** obtained results are validated with available experimental observations in open *** is observed that the sequence of in-plane failure and delamination varies by increasing the impact energy.
