Исследование характера процесса разрушения ортотропных пластин с концентраторами напряжений на базе вычислительного эксперимента

Исследование характера процесса разрушения ортотропных пластин с концентраторами напряжений на базе вычислительного эксперимента

Abstract

Рассмотрена модель разрушения ортотропного материала по совокупности критериев в плоском напряженном состоянии. Составлен алгоритм численной реализации процесса разрушения с учетом стадийности. Представлены результаты численного моделирования процессов разрушения ортотропных пластин в виде расчетных диаграмм деформирования, содержащих ниспадающую ветвь. Рассмотрены случаи реализации различных механизмов разрушения на основе использования совокупности критериев. Показано влияние стохастического характера прочностных свойств материала на процесс разрушения.

The multiple criteria failure model for the orthotropic material in plane stress is discussed. Numerical modeling algorithm of structural failure with account of multiple phases is presented. This work contains results for numerical failure modeling of the orthotropic plates in the form of calculating strain curves containing dependent branch. The cases of different failure mechanism realizations based on totality of failure criteria are considered. The influence of stochastic nature of material strength parameters on failure process is shown.
