К расчету процессов автофретирования толстостенных цилиндров с учетом повреждаемости материала

Abstract

В статті досліджується процес автофретування товстостінного циліндру з урахуванням пошкоджуваності матеріалу. Наведені рівняння теорії пружно-пластичного деформування з урахуванням континуальної механіки пошкоджуваності для моделі матеріалу з кінематичним зміцненням. Описаний алгоритм створення спеціальної моделі пластичності в ПК ANSYS та розраховане поле залишкових напружень, що виникають в товстостінному циліндрі після автофретування. Розрахунок проведений для задачі з прийняттям плоскої деформації. This paper presents autofrettage processes research in view of material damage. There are produced main equations of elastic-plastic theory in correspondence with Continuum Damage Mechanics for kinematic hardening material. Algorithm of user's material model creation for ANSYS software is described. Residual stress field is calculated for autofrettaged cylinder in the case of plane strain conditions.
