Title: Modelling of elastic constants of plasma spray deposits with ellipsoid-shaped voids
Author(s): Leigh, Sang Ha; Berndt, Christopher C.
Abstract: The five independent elastic constants of plasma spray deposits were calculated from constitutive equations and microstructural information (void aspect ratios and porosity) was gained from stereological analysis. The voids within the deposit were assumed to be ellipsoidal in shape. The structure of the deposit was considered to be transversely isotropic with respect to the spray direction, which requires five independent elastic constants of a stiffness tensor. Solid mechanics models containing ellipsoid-shaped voids were applied to obtain the five independent elastic constants of the deposits. The calculated elastic constants were compared to the experimentally determined values.
