Internal Fracture of Glass under Tri-Axial Tension Induced by Thermal Shock,
Abstract
Glass spheres were stressed internally in triaxial tension by thermal shock induced by up-quenching from 77k in liquid nitrogen to about 1000k in liquid tin to obtain rather uniform hydrostatic tension stress of about 3 x 10 to the 9th power dyne/sq cm. Among some 200 tested specimens, only 28, each of which contained a visible preexisting defect, were fractured. The rest showed strengths in excess of about 4.5 x 10 to the 9th power dyne/sq cm since no fractures nucleated either internally or at internal bubbles which concentrate the stress by a factor of 1.5.
