Description	In present work, three types of environmental barrier coatings fabricated by air plasma spray and containing a Si layer attached to SiC substrate plus 2 to 5 layers of different mullite/Y-ZrO2 mixtures are examined. To determine the level of residual stresses in the as-prayed coating/substrate systems a three dimensional finite element model is developed and also tested for same coatings but aged under high temperature and rich water vapor atmosphere. The model calculates the zones of maximum tensile stresses in the coatings which agree with experimental observation identifying the type, number and location of cracks.
