Abstract
This paper presents a finite-element procedure for the calculation of temperature and thermal stress fields during and after quenching of circular cylinders. An uncoupled thermomechanical problem is solved, neglecting the heal generated by inelastic deformation, but including the effects of temperature on mechanical properties. The analysis includes rate-dependent inelastic deformation and force-free boundary conditions at the ends of the cylinder. The analysis is flexible with respect to the choice of an appropriate viscoplastic constitutive model for material behavior. Numerical results for sample problems, as well as a comparison of measured and calculated temperature fields during quenching of an aluminum cylinder, are presented and discussed
