摘要
本文在Hoffman强度准则的基础上,采用复合材料层合板第K层中心穿透裂纹尖端附近的应力分量,得到一个计算复合材料层合板Hoffman塑性区尺寸因子的公式.
On the basis of the Hoffman strength criterion, the stress components in the vioinity of a central through crack tip of the k-th layer of composite laminate are calculated. A formula for the Hoffman plastic zone size factor of composite laminate is obtained. In this paper, the conclusion is correct. the concept is clear and the method is convenient. This makes the application of fracture mechanics criterion in composite laminate possible.
