Bifurcation and creep effects in a viscoelastic non-local damageable continuum
The conditions for localization in a material described by a non-local damage-based constitutive relation coupled with a Kelvin type creep relation are derived in a closed form. The inception of a localized mode is considered as a bifurcation into Preprint submitted to Elsevier Science 15 February 2006 a harmonic mode. The criterion of bifurcation is reduced to the classical form of singularity...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولElectrostatically Driven Creep in Viscoelastic Dielectric Elastomers
We utilize a nonlinear, dynamic finite element model coupled with a finite deformation viscoelastic constitutive law to study the inhomogeneous deformation and instabilities resulting from the application of a constant voltage to dielectric elastomers. The constant voltage loading is used to study electrostatically driven creep and the resulting electromechanical instabilities for two different...
متن کاملcreep and viscoelastic behaviour of human dentin
statement of problem: biomechanics of the human dentition is inherently complex. purpose: the aim of this study is to investigate, in vitro, the creep and the recovery of dentin under static uniaxial compressive stress conditions. materials and methods: specimens of cylindrical morphology were prepared from recently extracted non-carious lower molar teeth, such that the average tubule orientati...
