11/8/2009· Elastic properties such as Poisson''s ratio, elastic modulus, shear modulus and bulk modulus were determined from the measurements of sound velocities in Al/SiC p MMCs. Longitudinal velocity ( C L ), shear velocity ( C S ), Poisson''s ratio, elastic modulus, shear modulus and bulk modulus were studied as a function of the volume fraction of SiC.
