Abstract : The rate of change of the elastic strain energy with respect to notch depth is considered for edge notches or slots with a finite constant radius, rho at the tip. Numerical results are obtained for an edge slot in a semi-infinite sheet under tension. It is found that the slot can be considered as a crack of length L + 1.18 rho for this purpose. In finite sheet, this result is valid for small L/RHO RATIOS. (Author)
