Abstract
A viscoelastic–plastic mathematical model of the generation of thermal stress and strain in quenched steel plates has been extended to include the effect of stress on the characteristics of the martensite transformation. Stress dilatometry data are included for both the compressive and tensile cases and the results are introduced into the mathematical model either by using the concept of a reduction in yield stress or by use of an additional transformation strain. The use of either method produced an improved correlation between the calculated and experimentally determined residual stress and strain obtained after an oil quench, but this was at the expense of a reduced level of agreement in the case of water quenched material.
