Abstract

Femurs were obtained from 18 female baboons ranging in age from 6 to 27 years. A Vickers microhardness tester with a load of 25 gm was used to test the hardness of both the interstitial and haversian areas of the bone samples. Coupons measuring 2×3×21 mm were used for longitudinal fracture toughness tests and were affixed between two polymethyl methacrylate holders to obtain a single-layer sandwich specimen. The specimens were precracked and tested in an Instron tensile testing machine and fracture toughness was estimated. Another coupon measuring 2×4×25 mm was tested transversely in a three-point bending configuration. The specimen geometry and all measurements followed ASTM standard E399-90.
