Human femur bone was subjected to a uniaxial tension test. As a result of a series of experiments, the stress-strain curve shown in Fig. 13.42 was obtained. Based on the graph in Fig. 13.42, determine the following parameters: Elastic modulus, E. Apparent yield strength, sigma _y (use the offset method). Ultimate strength. sigma _u. Strain, epsilon _1, corresponding to yield stress. Strain, epsilon _2, corresponding to ultimate stress. Strain energy when stress is at the proportionality limit.
