本文对CSM-GRP层间剪切断裂用实验与分析方法进行了研究。用英国标准BS4994规定的双槽试件拉剪法测量了层间剪切强度(ILSS)。用有限元法计算了应力分布、损伤扩展和复合型应力强度因子。并讨论了BS4994规定的这一试验方法的可靠性。
In this paper, the experimental and analytical methods of CSM-GRP interlayer shear fracture are studied. The interlaminar shear strength (ILSS) was measured by the double-shear specimen tensile shear method defined in British Standard BS4994. The stress distribution, damage propagation and composite stress intensity factor were calculated by finite element method. The reliability of this test method as defined by BS4994 is also discussed.
