Abstract

ABSTRACT Internal remodeling of Bone models describes the process by which bone adapts its histological structure to change in the long duration of mechanical load areas. In orthopedics, wave propagation over bone is used in monitoring the rate of fracture healing. The present problem studies the effect of initial stress, rotation and magnetic field on wave propagation in long dry bones. A dry long bone has been considered as an orthotropic hollow cylinder. The equation of motion is solved in terms of displacements. Bisection method has been used to calculate the phase velocity of harmonic wave and frequencies of vibration in anisotropic long bone. Peculiar effects of rotation, initial stress, surface span and magnetic field on vibrations in long bone medium have been investigated and presented through graphs. The present study finds its applications in wave propagation and vibration test to determine the vivo properties of long bones. As an outcome, there is a significant effect of initial stress on long bone structure as compared to rotation and magnetic parameter. Findings may also be useful for theoretical development of orthopedic studies related to cylindrical poroelastic long bones.
