Аннотация
Дается математическое описание расчетной модели трещинообразования в листовом элементе конструкции при неоднородном напряженном поле. Принята модель зон предразрушения в состоянии пластического течения при постоянном напряжении. Краевая задача о взаимодействии зон ослабленных межчастичных связей материала в листовом элементе конструкции под действием неоднородного напряженного поля сводится к решению системы сингулярных интегральных уравнений. Интегральные уравнения далее сводятся к системе нелинейных алгебраических уравнений, для решения которой используется метод последовательных приближений. Определены размеры зон предразрушения и предельное значение внешней нагрузки, при котором происходит трещинообразование в листовом элементе конструкции.
