We measured bulk density and elastic wave velocities of composite materials, matrix and inclusions of which are epoxy resins and small iron balls, air bubbles and water drops, respectively.
Using the measured data, we calculated elastic constants and compared them with the Eshelby's theory on the elastic constants of composite materials.
We found that the agreement between the experimental and theoretical results are strongly effected by the shapes and distribution of the inclusions.
