... solution, the thermal stress response of the thick walled cylinder was solved. The time dependent variations of the temperature field—thermal stress field—were discussed, and the effect of cylinder radius ratio on the problem was given. The exploration in this paper will lay a theoretical reference...

...Hironori Tohmyoh; Masumi Saka; Yuichi Kondo This paper describes the “thermal opening technique” for enhancing the ultrasonic response of a tightly closed crack. In this approach, thermal stress is generated by cooling the part locally to reduce the crack closure stress in stainless steel plate...

...Vishnu Verma; A. K. Ghosh; H. S. Kushwaha The ball tank of the research reactor CIRUS is exposed to solar radiation. The ambient temperature undergoes seasonal and diurnal variation. The resulting thermal stress could be significant for the large structure. The temperature distribution has been...

...Akihiko Ohta; Naoyuki Suzuki; Yoshio Maeda Fatigue crack propagation properties of welded joints were investigated on steel plate for boilers and other pressure vessels. The fatigue crack propagation properties at 300°C became similar to those at room temperature when the thermal stress could...
