dc.description.abstract The volume element 0 V , being homogeneous at the macroscopic level, is considered to be composed of an infinite number of kinematically connected subelements with different thermorheological features. The internal constants reflecting simultaneously the heterogeneities of the stress and strain tensors fields at the microscopic scale are determined by the thermodynamic principles. The thermorheological features of the subelements are determined by proportional and isothermal tests of the thin-walled tubes strained by axial force and internal pressure. en_US
dc.description.abstract Un element de volum 0 V , omogen la scară macroscopică, se consideră compus dintr-un număr infinit de subelemente legate cinematic între ele şi cu diferite proprietăţi termoreologice. Constantele interiore care reflectă concomitent neomogenităţile câmpurilor tensorilor tensiune şi deformaţie la scară microscopică se determină în baza principiilor termodinamice. Proprietăţile termoreologice ale subelementelor se determină în baza solicitărilor proporţionale şi izoterme a tuburilor cu pereţi subţiri solicitaţi cu forţă axială şi presiune internă. ro
dc.description.abstract L'élément de volume 0 V , étant homogène à l'échelle macroscopique, est considéré comme étant composé d'un nombre infini de sous-éléments liés cinématiquement et avec des caractéristiques différentes thermorhéologiques. Les constantes internes, qui reflètent simultanément les hétérogénéités des champs de tenseurs de contrainte et de déformation à l'échelle microscopique, sont déterminées par les principes de la thermo-dynamique. Les propriétés thermorhéologiques sont définies par des tests proportionnelles et isothermes des tubes à paroi mince les chargées avec la force axiale et de la pression interne. fr
dc.description.abstract Макроскопически однородный элемент объема 0 V представляется в виде бесконечного числа подэлементов, кинематически связанных между собой и имеющих различные термореологические свойства. Внутренние константы, отражающие одновременно неоднородности полей тензоров напряжений и деформаций на микроуровне, определяются согласно термодинамическим принципам. Термореологические свойства подэлементов устанавливаются из опытов на пропорциональное изотермическое нагружение тонкостенных трубчатых образцов осевой силой и внутренним давлением. ru
