【摘要】 分别建立了具有穿透性裂纹和穿透性孔的复合材料受损层压板的剩余强度分析模型。对两类损伤结构均采用平均应力破坏判据计算剩余强度,通过对本文计算结果、NASTRAN计算结果与试验值的比较,表明本文编写的有限元程序具有较高的精确度,可以用来计算含缺口复合材料层压板的剩余强度。更多还原

【Abstract】 a numerical analysis model is developed for calculating the residual strength of composite laminate containing penetrated hole and crack. Finite element program is compiled to calculate the residual strength using average stress destroy criterion. The numerical analysis show that the result of this paper the result and of NASTRAN agree fairly well with the experimental results. It indicates that the program has higher precision and can be used to calculate the residual strength of composite laminate containing penetrated hole and crack.更多还原
