%X 运用蔡-吴逐步失效判据和黏聚接触模型建立弯曲加载下的T型接头的有限元模型。对复合材料T型接头在弯曲加载下的损伤机理和承载能力进行数值模拟。结合静态弯曲加载实验，揭示T型接头在弯曲破坏过程中的四种失效模式。T型接头的弯曲失效载荷的有限元模型计算结果与实测值吻合较好。</br>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.
