A quasi-three-dimensional lateral compressive analysis method for a composite cylinder

Abstract

This paper presents a lateral compressive analytical method for CFRP cylinders using the quasi-three-elements which represent fiber and resin respectively. Using this model, the behavior of a [ θ/ θ] sym ( θ = 15, 30, 45, 60) CFRP cylinder subjected to the lateral compressive load were simulated, and compared with experimental results. The quasi-three-dimensional model is found to be effective for the prediction of the load-displacement curve. For the damage propagation, the transverse crack and interlaminar delamination could be simulated independently. Moreover, the critical strength law using this model was proposed.
