Аннотация

Проведено математическое описание модели зарождения трещины в связующем композита при изгибе. Определение неизвестных параметров, характеризующих зародышевую трещину, сводится к решению сингулярного интегрального уравнения. Построена замкнутая система нелинейных алгебраических уравнений, решение которой позволяет прогнозировать трещинообразование в композите при изгибе в зависимости от геометрических и механических характеристик связующего и включений. Сформулирован критерий зарождения трещины в композите при действии изгибающих нагрузок.
