Abstract

After citing several experimental methods used for measuring three-dimensional effects in opaque and transparent cracked bodies, an integrated optical method is focused upon for obtaining two independent estimates of fracture parameters associated with linear elastic fracture mechanics (LEFM). Results of the use of these methods to study the effect of free surfaces upon the stress singularity of cracks intersecting them are presented and a means of interpreting the results within the framework of LEFM is suggested.
