✦ Synopsis
Cyclic growth rate of a surface crack is complicated by the three dimensional stress field around the crack and also by an interaction expected between the growth rate at every position on the contour. An analysis, based on the total energy around a smfoce crack, derived a correlation between strain energy rekase rate and cyclic increase in cracked area. And the correlation was confirmed by experiments conducted, with 9% Ni steel plate, under tension, bending and combined tension and bending.
