Abstract
Equations and a strain-gauge technique have been presented previously for the determination of the residual stresses in ceramic coatings. In the current work, the equations are rewritten in terms of simple form. The technique is extended to elevated-temperature environments. The stress-temperature relations of coated systems are modelled according to elastic and thermoviscoelastic theory. In addition, residual stress and thermal expansion coefficient measurements are performed on SiC coating-graphite substrate composites.
