Abstract

The purpose of this study is to develop a method for measuring elastic constants using a LFB acoustic microscope. For this purpose, a theoretical procedure for the estimation of Young's modulus and Poisson's ratio is introduced based on elastic theory. According to this procedure, experimental velocity measurement and elastic constants estimation are made by use of a LFB acoustic microscope. For the confirmation of the availability of this method, the estimated elastic constant is compared to measurements of elastic constants by other methods. The resulting estimated values of Young's modulus and Poisson's ratio obtained by the LFB acoustic microscope are highly accurate which confirms the usefulness of the elastic constant measurement system.
