TLDR

This paper presents a theoretical study of the stresses in an infinite circular solid cylinder subjected to rapid surface heating and cooling. A quasistatic, uncoupled, thermoelastoplastic analysis based on the incremental theory of plasticity is formulated, and a numerical procedure is developed for a method of successive elastic solutions. The material of the cylinder is assumed to have temperature-dependent properties and to be characterized by the Romberg-Osgood stress-strain relation. The transient and residual stress distributions are discussed in detail, along with variations of the equivalent stress and plastic strain with time.read more

On thermo-elastic-plastic analysis of heat-treatment processes including creep and phase changes
TL;DR: In this paper, a method is described for calculating the stresses in a body during heat-treatment and calculating the remaining residual stress distribution, with special attention given to the thermo-elastic-plastic material behaviour which is highly temperature-dependent.

TL;DR: In this paper, the elastic-plastic stress distribution of a solid disk due to non-uniform heat source under external pressure is investigated, and the exact solution presented is based on the usual assumptions of plane stress, Tresca's yield condition, its associated flow rule and linear strain hardening material behaviour.

Numerical Simulation of a Heat-Treated Ring Gear Blank
C. Mgbokwere,M. Callabresi +1 more
TL;DR: In this article, a two-dimensional simulation of the gear blank with the wall thinned where the teeth would have been located to represent the proper thermal mass was used to predict the distortions, microstructural phase changes, residual stresses, and hardness that occur during quenching using finite element techniques.

Elastoplastic thick-walled tubes of work-hardening material subject to internal and external pressures and to temperature gradients
TL;DR: In this article, the authors used Tresca's yield criterion and its associated flow rule to obtain solutions for the stresses, the elastic and plastic strains and the displacements when a thick-walled tube of work-hardening material is subject to internal and external pressures and its surfaces are maintained at different temperatures.
