Abstract : The stress field interactions between neighboring stress raisers (simulated flaws; a variety of edge notches, and holes) were investigated under uniaxial tensile load to obtain the basic information required for a fracture analysis of inhomogeneous brittle materials, such as ceramics. For the quantitative analysis of the stress distributions, photoelasticity techniques were used in transmission on Homalite CR-39 specimens. A numerical solution for the stress field of a doubly periodic array of elliptical holes was also obtained.
