Question

has shown that for an average value of K, 2 the notch sensitivity index is given + a/r), where a is a size" Hardrath have related a with the tensile strength of the steel. by particle size" dependent on the material and r is the notch radius 160 100 50 ks 200 0.0004 0.001 0.0042 0.012 Using these data, plot a curve of q versus r for steels of different strengths
