摘　　要：对三维机织角联锁结构复合材料进行了准静态拉伸测试,并通过有限元软件ANSYS/LS-DYNA对拉伸过程进行了有限元模拟。为了验证模拟结果的准确性,将模拟得到的结果与实验结果进行对比,结果表明:两者具有较好的一致性,材料的破坏模式也与实验结果相符,说明建立的有限元模型及设定的模型参数是正确的。In this paper,the 3D architecture composites conducted by the quasi-static tensile test,and with the finite element software ANSYS/LS-DYNA,a calculation of the quasi-static process is preceded.In order to identify the accuracy of the calculation,a comparison is conducted between the results gotten from the tensile test and the finite element calculation,it can be seen that they are highly consistent.The failures of the composites in the finite element calculation and the tensile test are similar too,so it can say that the model in this paper and the parameters of material are correct.In this paper the tensile process of the composites is simulated by the finite element method（FEM）,which has reference significance for the evaluating and the predicting performance of the 3D architecture composites.
