Unformatted text preview: = ~ (c) The strain-at-fracture (plastic) is 8 f = 0.43/10 = 9.043 The elastic strain just before fracture is the total strain minus the plastic strain: 0.54- 0.43 = 0.011 s = e 10 (d) At 20,000 lbs the total extension is -0.23 in that is composed of 0.06 in plastic extension and 0.17 in elastic extension. Thus, the plastic strain is fp = 0.06/10 = Q,QQ.Q and the elastic strain is: fe = 0.17/10 = Q.Ql1...
