Abstract

This paper describes an experimental technique whereby the behaviour of coatings, used to enhance surface properties of structures for thermoelastic stress analysis, may be assessed under a wide range of conditions. Established theoretical models are discussed and a novel description of the thermal response of coatings, with respect to changes in the substrate temperature, is presented. This description is then developed to include effects due to the thermoelastic response of the coating material and also the opacity of the coating to infra-red radiation. This work has substantial and wide ranging implications for the application of the thermoelastic technique. These are discussed briefly.
