Abstract
Stress relaxation is defined as the decay resulting from stress placed upon a material exposed to constant strain. Stress relaxation equipment designed and manufactured according to ASTM E328-86 was thus created to test this type of decay. Samples were extracted from animal femurs, in particular cortical bones from bovine around 24 months in age. The effect of various temperature on the stress relaxation behaviours of bovine femur samples was thus studied. The samples were examined for 1,800 seconds under the influence of three degrees of stress (25, 50, and 65 MPa respectively), with different temperatures of 29, 35, 40, and 50 °C used for each stress level; the stress results and diagrams for the effects of each stress were recorded and drawn separately.
