Abstract: | Following the work on the determination of dynamic elastic constants for the state of affairs around a single inhomogeneous ellipsoid, this work considers a fibrous composite whose inhomogeneity is increased on account of change in porosity or moisture content after the composite has been in service for some time. The added inhomogeneous phase, measured in terms of volume fraction of uniformly suspended particles in composite, is related to velocity measurement(s). The analysis is useful when the volume fraction of one type of inclusion phase is not known a priori. |
