Find the total toughness energy for a metal that experiences both elastic and plastic deformations. The modulus of elasticity is 107.2 GPa, and elastic deformation terminates at a strain of 0.009. For plastic deformation, assume that the relationship between stress and strain is described by T = 1.66xKn, in which the values for K and n are 1453 MPa and 0.175, respectively. Furthermore, plastic deformation occurs between strain values of 0.009 and 0.67, at which point fracture occurs

Your boss is convinced and decided that the customers will save a lot of energy in processing material ifthe molecular weight of the polymethyl methacrylate (PMMA) manufactured is lower from 250,000g/mol to 150,000 g/mol.

Calculate the stain and the corresponding stress at that elongation value. b. Afterward, the specimen is released to zero stress level, how does the final length of the specimen compare with its original length? How much plastic deformation remains if it exists?
For a tensile test it can be shown that the percent cold work (%CW) is related to strain according to the following relationship: %CW=(εε+1) × 100 Using this equation, compute the percent cold work experienced by naval brass (for which the stress-strain behavior is shown in the Animated Figure 6.12) when a stress of 415 MPa (60190 psi) is applied.
