【 摘 要 】

Based on ABAQUS/Explicit, a three-dimensional finite element model of composite squre tube with single bolt was established. The criteria of Hashin classification failure was used to distinguish the fiber tensile, fiber compression and matrix stretching of composite square tube under local compression loading. The four modes of matrix compression are used to obtain the load-displacement curve of the model, which is used to analyse the progressive damage failure process of the composite square tube single nail connection during quasi-static compression, and to estimate the strength of the joint.
