| Abstract: | 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. |
