摘要

考虑了一种解决确定复合材料板失效概率和失效载荷大小的概率（统计）特征问题的方案。板状结构是一个具有随机分布的刚性棒夹杂物的平坦均匀矩阵。夹杂物的几何参数被认为是具有给定概率分布规律的独立随机变量。接收并给出了失效载荷分布函数、失效概率、平均值和失效载荷分散度的表达式。用图表研究了它们对应力状态类型、夹杂物数量和基体泊松比的依赖性。

A Probable Approach to Reliability Assessment of Reinforced Plates

A scheme for solving the problem of determining the probability of failure and probabilistic (statistical) characteristics of the failure loading magnitude of a composite material plate is considered. The plate structure is a flat homogeneous matrix with stochastically distributed rigid rod inclusions. The geometric parameters of inclusions are considered independent random variables with given probability distribution laws. The expressions for the failure loading distribution function, the probability of failure, the mean value, and the dispersion of the failure loading were received and presented. Their dependence on the type of stress state, the inclusion number, and matrix Poisson’s ratio were studied graphically.
