Abstract

Bone filled with marrow is modeled as poroelastic bore filled with a fluid in the frame work of Biot's theory in wave propagation phenomena. Axially symmetric unattentuated waves are considered. Frequency equations are derived in the cases of permeable boundary and impermeable boundary, and are found to be dispersive. The existing data of bony materials has been exploited. Phase velocity versus ratio of wavelength to bone diameter curves are plotted. From this model and analytical results, some conclusions are drawn.
