a. Cyclic fatigue (low cycle) in metals is characterized by the equation Ne = (C/Aɛp), where Ne = number of cycles to failure, Aɛ is the plastic strain range, C is a proportionality coefficient, and ß is the fatigue ductility exponent. For ß = 0.5, what happens to the fatigue life if the plastic strain range doubles? What are equations of the type given above called? (30 points) c. Find the spacing between the set of planes whose Miller indices are (222) in the base centered orthorhombic lattice. (Assume : b = a/2 and c = a/13).
