“…This assumption is valid in the elastic regime if Poission's ratio u =1/2. However, this assumption is more valid when plastic deformation is much greater than elastic deformation which can be also seen from the relation for the dilatancy If u = 1/2 then 8 = 0 which means that the material is incompressible (Padmanabhan et al (2001)). In the case where the constant volume assumption holds, the following relationships can be shown to be true for uniform strain:…”

“…Кроме того, освоена техноло-гия изготовления из того же сплава и по той же техноло-гической схеме сферических сосудов высокого давления для крылатых ракет среднего радиуса действия, а также коррозионно-стойких поплавков контакторов уровня жидкости для химической промышленности. Посколь-ку изделия аналогичного назначения производятся не только на Тайване, имеется множество публикаций, посвященных анализу напряженно-деформированно-го состояния и расчету основных технологических па-раметров процесса СПФ листового проката в матрицу цилиндрической формы, см, например, [27][28][29][30][31][32][33][34][35][36][37]. Каждый год появляются все новые и новые публикации, в работу вовлечены исследователи США, Японии, России, Индии, Китая, Кореи, Тайваня, Сингапура и других стран.…”

“…На это обсто-ятельство обращают внимание авторы работ [34,35]. По их мнению, исторически сложилось так, что явление сверхпластичности отметили (т.е.…”

“…There have of course been numerous attempts to develop models to represent material behaviour under SP conditions [4]. Many such models take either a power law or hyperbolic sine form [4,5]. Such approaches, while valid within some particular range of temperature and strain rate, will however become invalid outside of the deformation regime associated with SP.…”
