Abstract
An important consideration in design is the determination of residual stresses developed during heat treatment of steel. By selecting an appropriate heat treatment technique, one can control the level of residual stresses in the components. Obviously beneficial residual stresses in the material increase the life of components. On the other hand, the unexpected failure of components that is later attributed to detrimental residual stresses is not uncommon.In this paper, residual stress distribution in a quenched long solid cylinder with temperature dependent properties is evaluated. Using three different speeds of cooling, the level of residual stresses for each speed was determined and compared with the others. From the stresses calculated, it was found that the tensile and tangential residual stresses are more sensitive to the speed of cooling than the radial one. For theoretical analysis a quasi-static uncoupled thermoelastoplastic analysis, based on incremental theory of plasticity, is developed and a ...
