On determination of residual stresses in coatings from the measured longitudinal deformation of a strip substrate
This paper presents an algorithm for the calculation of initial stresses from the longitudinal deformation of a straight strip substrate, measured during the simultaneous deposition or dissolution of a coating on the two sides of the substrate. The possibility of prestressing the substrate by an elastic element (spring, semiconductor) is taken into account. An example of application is presented.
