摘要 以渐进损伤方法和双线性内聚力模型为理论基础,结合ABAQUS6.8用户子程序USDFLD对轴向拉伸载荷作用下轴棒法C/C复合材料的破坏模式及载荷进行了预测,对比了试验结果与预测结果。结果表明:本方法可以准确预测轴拉载荷作用下轴棒法C/C复合材料的破坏模式。 In the base of progressive damage method and bilinear cohesive model,destruction mode and limit load of C/C composite made by axial rod method under axial tension load were forecast by using user defined program USDFLD of ABAQUS6.8.The experimentresultand forecast result were compared.As a result,fracture mode of ax-ial rod carbon/carbon composite can be accurately forecast by using the method put forward in the paper.
