Abstract
A numerical procedure of assessment of Thermal Stress Intensity Factors (TSIFs) of an edge crack in a strip made of Functionally Graded Material (FGM) subjected to thermal cooling process was elaborated. In order to perform it own subroutines in ABAQUS code were created. The analyzed ZrO2+Ti6AlV material in the form of the FGM is applied as cylinder liners (Thermal Barrier Coatings TBC) of aircrafts engines and is subjected to extremely quick temperature changes during the engine work. Therefore estimation of the TSIF to determine fracture process in the ZrO2+Ti6AlV material is important for designing of the structural element thermal protection and further safety of aircrafts passengers.
