Effect of Local Residual Stress on Crack Propagation in Thermal Tempered Glass

Abstract

The crack propagation in thermal tempered glass specimens having 9 continuous patterns of local residual stress has been studied. The thermal tempered glass specimens were made with the solid contact method and the immersing method using silicone oil.
The results show that crack velocity, fragment density and spline were dependent on local residual stress pattern and impact point.
