Specimens of human cortical bone tissue were subjected to a simple tension test until fracture. The test results revealed a stress-strain diagram shown in the following figure, which has three distinct regions. These regions are an initial linearly elastic region (between 0 and A), an intermediate nonlinear elastoplastic (between A and B), and a final linearly plastic region (between B and C). The average stresses and corresponding strains at points O, A, B and C are measured as: Point Stress...

Question 5: Draw a typical stress-strain relationship (graph) for steel subjected to tension. On that graph, show the initial tangent modulus (slope only), proportional limit, elastic limit, the yield strength, ultimate strength and rupture stress. Also indicate the area that would be used to determine the modulus of resilience. (2+6+3 =11 Points)

1. (5 pts) If a steel bar subjected to uniaxial tension enters into t the plasticity region of the stress-strain curve, which of the following statement is ALWAYS true? (select all that apply) a. Stress in the bar has exceeded yielding strength: b. Stress in the bar has exceeded proportional limit; c. The total strain can d. The plastic strain can be fully recovered if tensile load is fully released; be fully recovered if tensile load is fully rel released;...

1.6 points) A tensile test specimen having a diameter of 10 mm and a gange length of 50 mm wa. tested to fracture. The stress-strain curve from the tension test is shown below. Labeling your points and showing the necessary steps, along with the corresponding calculations, find the following magnitudes: (a) Modulus of Elasticity, E = (b) Ultimate Strength = (e) Yield stress (0.2% offset method), (d) If the shear modulus of elasticity of the material is 28 GPa, determine...

A Grade 2 Titanium tension test specimen has a diameter of 12.60 mm and a gage length of 50 mm. In a test to fracture, load and deformation data obtained during the test are given in the accompanying table. Plot the stress strain relationship then, determine the following: (a) the modulus of elasticity. (b) the proportional limit. (c) the yield strength (0.20% offset). (d) the ultimate strength. (e) the fracture stress. (f) the true fracture stress if the final diameter...
