摘要：Axial compression test is performed on an advanced grid stiffened (AGS) composite cylinder and the progress of failure is recorded by strain sensors and LVDT sensors. Failure prediction on the AGS composite cylinder is accomplished by a cyclical symmetrical finite element (FE) model which can improve the efficiency of numerical simulation. Numerical results and experimental data are compared to verify the proposed model. Various failure prediction criterion based on degradation principles for the AGS composite cylinder are employed to investigate the accuracy of the proposed model. (C) 2011 Elsevier Ltd.
