...J. P. Shingledecker; R. L. Battiste; P. Carter The DOE/OCDO sponsored Ultrasupercritical Steam Boiler Consortium is conducting thermal shock tests on austenitic and nickel-based materials to assess their use in thick-section boiler components. This paper describes the tests on CCA617 (a controlled...

...Yingwei Yun; Il-Young Jang; Liqiang Tang This paper presented the stress distribution in a thick walled cylinder under thermal shock. Dirac function was introduced to model thermal shock. An analytical solution of the temperature field was obtained by Laplace transform. Based on the temperature...

...A. E. Segall; D. Engels; A. Hirsh Thermoelastic states as they pertain to thermal-shock are difficult to determine since the underlying boundary conditions must be known or measured. For direct problems where the boundary conditions such as temperature or flux, are known a priori, the procedure...

... the potential crack-opening stresses throughout the body. Using the found stresses and a weight-function approach, stress-intensity factors were then determined for both edge and semi-elliptical cracks under an arbitrary thermal-shock. When compared to other methods for various thermal scenarios, the method...

These subclad cracks should be assumed for a safe operation under normal conditions and faulted conditions such as pressurized thermal shock (PTS). There are several elastic stress intensity factor (SIF) solutions for subclad cracks which are used...
