Abstract

In the previous report, thermal stresses and deformation of a steel strip subjected to local heating were analysed by the finite element method, and useful knowledge on temperature, strain and stress distributions was obtained.<BR>In this continued report, the effects of latent heat, the breadth of the strips and external restraint on these distributions were investigated.<BR>The results obtained are as follows.<BR>1) The temperature distribution in the vicinity of melting zone can be evaluated more accurately by considering latent heat.<BR>2) The effects of latent heat on stress distributions as well as deformations of the strips are considerably small.<BR>3) The maximum tensile residual stress occurs near the boundary of heated region, and shows a tendency to increase as the breadth of the strips increases.<BR>4) The angular distortions of the strips can be evaluated simply by using the beam theory provided that an amount of inherent strain in the heated region is estimated properly.<BR>5) Removing end restraints after the completion of thermal cycle, it is possible that a large amount of deflection may occur compared with that in free condition.
