What is Thermal Barrier Coatings Fracture Toughness Analysis about?

This document introduces a new fracture toughness test method for evaluating the fracture resistance of multilayered thermal barrier coatings (TBCs). The test models an internal crack within the coatings, rather than an edge crack as in other methods. Computational and experimental analysis showed that internal defects significantly weaken TBCs, while debonding resistances of the bond coating and interfaces are higher. A separate analysis found that when an embedded crack size is the same as the coating thi
