  1. Example 6.1 Tensile Testing of Aluminum Alloy Convert the change in length data in Table 6-1 to engineering stress and strain and plot a stress-strain curve.

  2. (c)2003 Brooks/Cole, a division of Thomson Learning, Inc. Thomson Learning™ is a trademark used herein under license. Figure 6.10 The stress-strain curve for an aluminum alloy from Table 6-1

  3. Example 6.1 SOLUTION

  4. Example 6.3 Young’s Modulus of Aluminum Alloy From the data in Example 6.1, calculate the modulus of elasticity of the aluminum alloy. Use the modulus to determine the length after deformation of a bar of initial length of 50 in. Assume that a level of stress of 30,000 psi is applied. Example 6.3 SOLUTION

  5. Example 6.4 Ductility of an Aluminum Alloy The aluminum alloy in Example 6.1 has a final length after failure of 2.195 in. and a final diameter of 0.398 in. at the fractured surface. Calculate the ductility of this alloy. Example 6.4 SOLUTION

  6. Example 6.5 True Stress and True Strain Calculation Compare engineering stress and strain with true stress and strain for the aluminum alloy in Example 6.1 at (a) the maximum load and (b) fracture. The diameter at maximum load is 0.497 in. and at fracture is 0.398 in. Example 6.5 SOLUTION

  7. Example 6.5 SOLUTION (Continued)
