Class 20 and class 60 gray cast irons have tensile


Class 20 and class 60 gray cast irons have tensile strengths of about 20 and 60 ksi respectively. Assuming that the fractures start from graphite ?akes and that the ?akes act as preexisting cracks, use the concepts of Grif?th analysis to predict the ratio of the average graphite ?ake sizes of the two cast irons.
