Three-dimensional photoelasticity: stress distribution around a through thickness crack,ding region of the material. The redistribution of stresses and strains around the crack has been the subject of many past discussions both experimentally and analytically. Much of the work, however, has been limited to two-dimensional stress analyses because of the complexity of three-dimensional elasticity problems.

This effect was first observed by Sir David Brewster in 1816 and is known as temporary double refraction. When such materials are loaded and observed in a polarized light field, temporary double refractio

The technique yields high accuracy of measurement, but is still simple to apply. Besides the usual equipment for (high speed) photography, only a point light source is required. Mer

With an appropriate experimental arrangement, interference of light from opposing crack surfaces produces the well known Newton’s fringes which are lines of equal crack opening displacement. Since the opening displacement is closely related to the stress intensity factor .,
