1125 Effects of Calcium Content on the Mechanical Strength of Rat Femur
Details
Cylindrical and dumbbell-shaped specimens were made from the diaphyese of rat femurs. These specimens were partially demineralized by immersion in a 0.5M EDTA solution. For the specimens, compressive and tensile tests were performed. With the decrease in the calcium content, the compressive strength decreased and the compressive strain at failure increased. The tensile strength decreased in the same manner as the compressive strength. On the other hand, the tensile strain at failure did not change with the decrease to about 50% in the calcium content.
