determine the following: a. Modulus of resilience b. Toughness Hint: The toughness (ut) can be determined by calculating the area under the stress-strain curve C. Ef Ut= ode 4-1001 where & f is the strain at fracture. The preceding integral can be approximated numerically by using a trapezoidal integration technique: u = u = i=1 1 2 (0 +0i-1) (ei - Ei-1) If the specimen is loaded to 40 ksi only and the lateral strain was found to be -0.00057in./in., what is Poisson's ratio of this metal? d. If the specimen is loaded to 70 ksi only and then unloaded, what is the permanent strain? determine the following: a. Modulus of resilience b.
