Abstract
The Ivlev–Sporykhin continuum model, which is a model of a hardening elastoviscoplastic solid, is considered in this study. The model takes into account both reversible and irreversible deformations to investigate evolutionary processes occurring in a hollow sphere under the influence of a time-dependent temperature field. During the solution of this problem, an analytical expression for the temperature distribution within the body was derived. A generalized tree of evolution of regions of elasticity, plastic flow, unloading, and re-plasticity was also constructed. Expressions for the radial components of stress and displacement in these regions were also developed. Four rheological models were compared, taking into account the various properties of the medium.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
