ABSTRACT	A series of fundae outer surface was heated by an image furnace to simulate the effects of a high temperature gas flow,while the inner surface was cooled by forced convection of air.Then as a mechanical load,a one dimensional tensile load was applied in the axial direction of the pipe by a tensile loader apparatus while sustaining the said thermal load.This mechanical load is considered a substitute for the centrifugal force arising in rotating members.Through this simulation method,mechanical damage was assessed.This paper concerns the descriptions of the evaluation test method,some analytical considerations about the test piece under certain conditions and the results from the early tests using stepwise graded material (non-FGM) conventionally introduced for the thermal barrier coating.
