A MODEL OF DESCRIBING CREEP STRAINS AND POROSITY EVOLUTION FOR A HOLLOW CYLINDER AFFECTED BY INTERNAL GAS PRESSURE

DOI: 10.17804/2410-9908.2023.5.006-014

Two plane-strain states of two identical hollow cylinders are considered, where one is made of a material with porosity evolution and the other is made of an incompressible material. For each hollow cylinder, the process of inflation begins from an undeformed state and ends as soon as the external boundary radius reaches a certain set value. In the assumption that the porosity increases and reaches its highest value at the outer boundary radius, the two hollow cylinders are compared in terms of their strains and stresses.

Keywords: hollow cylinder, internal pressure, creep, porosity

МОДЕЛЬ ОПИСАНИЯ ДЕФОРМАЦИЙ ПОЛЗУЧЕСТИ И ЭВОЛЮЦИИ ПОРИСТОСТИ ДЛЯ ПОЛОГО ЦИЛИНДРА ПОД ВОЗДЕЙСТВИЕМ ВНУТРЕННЕГО ДАВЛЕНИЯ ГАЗА

Рассмотрены два плоских деформированных состояния двух одинаковых полых цилиндров, где один изготовлен из материала с эволюцией пористости, а второй – из несжимаемого материала. Процесс раздувания для каждого полого цилиндра начинается из недеформированного состояния и завершается достижением внешним граничным радиусом некоторого заданного значения. В предположении, что пористость возрастает и на внешнем граничном радиусе принимает свое наибольшее значение, приведено сравнение деформаций и напряжений двух полых цилиндров.

Ключевые слова: полый цилиндр, внутреннее давление, ползучесть, пористость
