| Abstract: | This paper makes study of the design of two direction stress specimen which is made of 3D carbon/carbon composite material. Through FEM calculation the conclusion of uniform stress field in the marked central area is perfected. The formula of stress calculation in the marked central area is improved.The affection of thick ratio and bypass, and the stress concentrition are analysized. The paper well solves the problems in the test and presents important bases for the strength criterion of other similar materials. |
