Thermal Stress and its Residual Stress of Rectangular Plate under One-dimensionally distributed Temperature

Abstract

Many reports for residual stress have been published, but they cannot be said successful togive a solution for this problem. To discuss the characteristics of residual stress, we mustconsider not only its magnitude but its process of growth. For the first step of this idea, we dealt with a rectangular plate under one-dimensionally distributed temperature as shownin Fig. 4, In this case thermal stress and its residual stress act practically only in thedirection of heating. In experiment breadth 5mm on the centre line of test piece 300×110×2.3mm was heated instantaneously from both sides and residual stress was measured byHeyn's method.
On the while, thermal stresses for every momentary temperature distribution were calculated by author's plastic theory and the residual stress was obtained for the last course. These results are shown in Fig. 10 & 13.
An example for the two-dimensionally distributed stress will be discussed in the second report.
