In this paper, we develop a thermodynamically consistent description of the uniaxial behaviour of thermoelastoplastic materials that are characterized by a constitutive law of the form (x; t) = P["; (x; t)](x; t) , where " , , denote the elds of strain, stress and absolute temperature, respectively, and where fP[ ; ]g >0 denotes a family of (rateindependent) hysteresis operators of Prandtl-Ishl...

all the producing and assembling processes exert residual stress on the pieces that may lead to structural failure. therefore, calculating the residual stress in such structures has been common in recent years. in this article, distribution of temperature and residual stress resulting from arc welding in three-pass butt joint in p91 austenitic stainless steel pipes is calculated and estimated u...

Introduction. Cylindrical and spherical shells are extensively used in engineering. They face internal and/or external pressure heat. Stresses strains distribution elastoplastic has been studied by many scientists. Numerous works involve the use of von Mises yield conditions, maximum shear stress, reduced stress. These condi- tions do not include dependence on first invariant stress tensor sign...

Frequently, the case of finite strain anisotropy, particularly, the case of transversal isotropy, is applied to biological applications or to model fiber-reinforced composite materials. In this work the multiplicative decomposition of the deformation gradient into one part constrained in the direction of anisotropy (fiber direction) and one part describing the remaining deformation is proposed....
