Abstract
A series of frozen stress experiments were conducted on a rocket motor grain geometry containing a natural surface flaw of varying aspect ratios in order to study the stress intensity factor distribution along the flaw border and to estimate the loss of the inverse square root singularity when the crack border intersects the inner star surface at right angles. By applying a refined optical method, the photoelastic data are converted into classical stress intensity factors resulting from the three dimensional stress state existing at the inner surface to indicate the nearly uniform distribution of the stress intensity factors along the crack border.
