... expansion joint spring rate thermal stress tubesheet ASME VIII-1 TEMA The design of Flanged and Flued type expansion bellow (i.e., thick wall expansion bellow) is very complex as it closely related to tubesheet design and involves an evaluation of pressure capability, stress due to deflection...

...Hengliang Zhang; Danmei Xie; Jin Jiang Online monitoring of temperature and thermal stresses is an important way to ensure the safety of power plants considering fatigue and creep damages. The effect of online monitoring is determined by the accuracy and calculating time of monitoring models...

... on the small deformation theory and Tresca's yield criterion an axisymmetric, plane strain, elastoplastic, thermal stress analysis for a cylindrical vessel made of functionally graded elastic, perfectly plastic material is offered. Elastic modulus and yield strength coefficients are assumed to be power...

... causes excessive thermal and mechanical stresses in the drum shell and attachment structures. It has been recognized that the common failure mechanisms for coke drums are related to the low cycle fatigue, bulging, and cracking caused by these cyclic thermal stresses. The objective of this study...

... 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...
