Further work on these lines has revealed that such modes can be similarly transmitted through isotropic media. This offers a new method of obtaining the entire frequency spectrum of a given plate, and therefore its elastic constants, even when it is available only as a small fragment. Using a...
These are the data employed in the determination of the elastic constants for cancellous bone recorded in following text. In this method, the actual matrix material of the trabeculae comprising the bone specimen is assumed to have an axial Young's modulus Et. The value of Et may be fixed ...

The differential equations about shear and bulk moduli of foam plastics have been derived by differential scheme of composite mechanics. And the couple equations have been solved by using the relation of elastic constants for isotropic foam plastics. The

It is reasonable to assume that, in the bulk, the overall behavior of unidirectional graphite/epoxy composites is the same as that of a homogeneous, transversely isotropic material with its symmetry axis along the fiber direction. Then the linear elastic response of the material can be described ...
