Abstract
A method for estimation of the elastic moduli of porous ceramics solely based on ultrasonic longitudinal wave velocities is proposed. The method is based on a polynomial correlation between ultrasonic shear wave and longitudinal wave velocities of a given porous material. It is also shown that variations of Poisson's ratios for porous material with longitudinal wave velocities agree with the predictions of Mori‐Tanaka mean field approach. The method provides a simplified route to quantitative non‐destructive evaluation of the elastic moduli of porous material.
