The book describes a systematic stochastic modeling approach for assessing thermal-fatigue crack-growth in mixing tees, based on the power spectral density of temperature fluctuation at the inner pipe surface. It shows the development of a frequency-temperature response function in the framework of single-input, single-output (SISO) methodology from random noise/signal theory under sinusoidal input. The frequency response of stress intensity factor (SIF) is obtained by a polynomial fitting procedure of thermal stress profiles at various instants of time. The method, which takes into account the variability of material properties, and has been implemented in a real-world application, estimates the probabilities of failure by considering a limit state function and Monte Carlo analysis, which are based on the proposed stochastic model. Written in a comprehensive and accessible style, this book presents a new and effective method for assessing thermal fatigue crack, and it is intended as a concise and practice-oriented guide for all undergraduate students, young scientists and researchers dealing with probabilistic assessment of structural integrity.1660+543.2349 f-910.2986;f +736.5647 f a€“ 234, 9905 faquot; (E3) (E4) h4(f)=-43.4634 +281.9147f-341.3181 f* +18.4.2000f -35.7704 faquot; (E5) [1] API 579 Fitness-for- Service-API Recommended Practice 579, 1st edn, American Petroleum Instituteanbsp;...
