Today's competitive world economy is creating an indispensable demand for increased efficiency of engineering components that operate in harsh environments (i.e., very high-temperature, corrosive, or neutron irradiation environments), for applications in the energy, automotive, aerospace, electronics, and power industries. Increased research is being done on thermal barrier coatings (TBCs) for protecting such components, since the versatility of manufacturing techniques and the scale of deployment result in increased life, economics, performance, and durability. This review focuses on the advances that led to using TBCs for component life extension and, more recently, as an integral part of advanced component design for high-temperature and other types of harsh environments, such as those found in nuclear-related applications. Factors that led to state-of-the-art advanced coating-fabrication techniques [e.g., electron-beam physical vapor deposition (EB-PVD), plasma spray deposition, and electrophoretically deposited TBCs, as well as functionally graded material (FGM) manufacturing] have also been emphasized in current coating R&D. This review explores the current state of TBCs, i.e., the latest advances regarding their fabrication and performance, associated challenges, and recommendations for their future use in aerospace, nuclear, high-temperature, or otherwise harsh environments.

“…Various engineering issues should be resolved using numerical techniques. Within the framework of linear fracture mechanics, several numerical methods have been proposed to evaluate the stress state in the vicinity of the crack, based on the determination of the stress intensity factors (Blackburn, 1973;Mohammed et al 2019;Ait Ferhat and Boulenouar, 2020;Blandford et al 1981). Among these methods is the interaction integral method which has been the subject of several studies, used to analyze the problem of cracking in mixed-mode (Yu et al 2009;Kim and Paulino, 2003;Réthoré et al 2005;Ammendolea et al 2021;Feng et al 2020).…”

The objective of this study is to present numerical aspects related to the implementation of the interaction integral method for the purpose of determining the stress intensity factors in mode I and mixed-mode crack problems of functionally graded materials (FGM) and homogenous materials for a different form of cracking. This numerical development is based on the use of the finite element method (FEM), by the coupling of the Ansys-Matlab calculation codes. To validate the accuracy and reliability of the approach, the results obtained will be compared with other numerical results in the literature. The interaction integral method is one of the methods most compatible with the formulation of the finite element method. Therefore, we are interested in this study, in terms of the presentation of necessary steps which allow the resolution of a problem by finite elements for the mechanical problems. It is very important to note that the principle of the implementation of the â€œIntegral Mâ€ technique is using scripts based on the coupling of two commercial software.
