Abstract

The deterioration of the mechanical properties with aging is the major caused of the fracture of bone in elder population. The elastic modulus (Young’s Modulus) deteriorated in aging bones. An understanding is essential to known how elastic modulus degrades in aging bones. In the present study tensile testing experiments on the bovine hip joint bone have been performed in both longitudinal and transvers directions to investigate the effect of age on the elastic modulus on bovine hip joint bone. The samples for testing are taken from the age groups 1-5 years. From these experiments the elastic modulus is determined both in longitudinal and transvers direction. It is found that the elastic modulus deteriorated both in longitudinal and transvers directions with increasing age. It is investigated the deteriorated is higher in transvers direction as compared tolongitudinal direction.
