Abstract
⺠TBC failure occurs at a critical value of strain energy within the TGO layer only. ⺠A lower bound value of 55 J.mâ 2 is suggested. ⺠Transformation strains within the bondcoat are not significantly damaging. ⺠Mechanical instability of the bondcoat is restricted with an adherent topcoat. ⺠TGO growth induces out-of-plane tensile stresses on non-planar bondcoat surfaces.
