“…Waxler and Napolitano [1,2] have found the photoelastic constants for some standard optical glasses. Rabukhin [3] has studied the photoelastic constants of germanate glasses containing lead and bismuth oxides. Primak and Post [4] have measured the photoelastic constants of silica using an interferometric technique involving a calibrated graduated quartz wedge.However, Elasto-optic constant used with DGS is different from photoelastic constants used with photoelastic.…”

Elasto-optic constant is an important parameter for stress measurement by digital gradient sensing method (DGS). In this paper, Elasto-optic constant is measured using an edge-cracked three-point bending specimen. Elasto-optic constant is related to known stress intensity factors and specimen thickness. The full-field angular deflections around the crack-tip are measured using DGS. And then Elasto-optic constant were calculated from the experimental data by linear-least squares method.

“…The photoelastic constants of germanate glasses containing lead and bismuth oxides were studied by Rabukhin [ 7 , 8 ] where he suggested that the photoelastic and elastooptic data could be used for the light and acoustic lines of acoustooptical devices. He proposed that the high photoelastic constants of lead bismuth germanate glass can be achieved through high refractive index and low modulus of elasticity.…”

This paper reports the rapid melt quenching technique preparation for the new family of bismuth-lead germanate glass (BPG) systems in the form of (GeO2)60–(PbO)40−x–(½Bi2O3)x where x = 0 to 40 mol%. Their densities with respect of Bi2O3 concentration were determined using Archimedes’ method with acetone as a floatation medium. The current experimental data are compared with those of bismuth lead borate (B2O3)20–(PbO)80−x–(Bi2O3)x. The elastic properties of BPG were studied using the ultrasonic pulse-echo technique where both longitudinal and transverse sound wave velocities have been measured in each glass samples at a frequency of 15 MHz and at room temperature. Experimental data shows that all the physical parameters of BPG including density and molar volume, both longitudinal and transverse velocities increase linearly with increasing of Bi2O3 content in the germanate glass network. Their elastic moduli such as longitudinal, shear and Young’s also increase linearly with addition of Bi2O3 but the bulk modulus did not. The Poisson’s ratio and fractal dimensionality are also found to vary linearly with the Bi2O3 concentration.

“…Of particular technological interest are zero stress-optic glasses, in which, as the name implies, the coefficient vanishes. It is well-known that glasses with high lead oxide content may have zero and even negative stress-optic response [1]; this behavior can also be induced by thallium oxide and bismuth oxide [2][3][4][5].…”
