弯曲载荷作用下复合材料 T 型接头的失效分析
Failure analysis of composite T-joints under bending load
摘要
Abstract
A finite element model of the composite T-joints under bending load was established.The Tsai-Wu failure criterion and a cohesive zone model were used to simulate and analyze the failure mechanisms and carrying capacities of the composite T-joints under bending load.By static bending experiments,four failure modes have been investigated during bending failure processes of the composite T-joints.The maximum bending load of the T-joint calculated by finite element model methods was consistent well with experimental results.关键词
