Определение вероятности безотказной работы конструкций из полимерных материалов
2004
In the paper for analysis and simulation of stress-strain state of polymer constructions a probabilistic approach is used, which reflects the fact that for real materials a deviation of their property values always exists, for constructions a deviation of dimensions from their nominal values, for loads a deviation from average exploitation values. Using methods of the probability theory and mathematical statistics the analysis of stress-strain state parameters of constructions gained from numerical and natural experiments with material property deviation is carried out. On the basis of these data probability fields of non-failure operation of a certain construction are obtained.
