A large flat plate is subjected to constant-amplitude uniaxial cyclic tensile stresses of a maximum stress...
A large flat plate is subjected to constant-amplitude uniaxial cyclic tensile stresses of a maximum stress of 147 and a minimum stress of 32 MPa. If before testing the largest surface crack is 0.98 mm and the plain-strain fracture toughness of the plate is 33.4 MPa m1/2, estimate the fatigue life of the plate in cycles to failure. For the plate, m = 3.7 and A = 5.0 x 10-12 in MPa and meter units. Assume Y = 1.14

Question 15 (1 point) A material element is subjected to plane stress conditions. The stresses at the point of interest are as follows (units of MPa are assumed): 0x =-87 Oy =36 Txy =-77 Determine the normal strain in the z-direction, Ex, in microstrain (to one decimal place). So if the value is 18.4 E-06, just enter "18.4". You may assume Young's modulus is 72 GPa and Poisson's ratio is 0.3 for this material.
