Title: Determining a Method to Pressure Test a Novel Type of Glass

Abstract

A novel type of glass made with a double ion exchange process is more reliable and fractures in a unique manner compared to glass currently available in the market. The novel glass is unique because it disintegrates into a powder instead of fracturing into shards and splinters, and it fails over a very narrow range of stresses. Potential applications for this glass include using it in removable valves because the powdered glass does not produce obstructions when it breaks, and in other applications that require safety glass. A 20,000-psi MTS pressure system was used to determine the possible techniques for pressure testing the strength of a collection of disk-shaped glass samples. Ordinary (i.e., not ion exchanged) glass samples, 0.962 inches in diameter and 0.07 inches thick, were fractured with linearly increasing pressures to determine the best methods. The best method for testing novel glass samples, with the same size and shape as the ordinary glass, will be implemented. The final results of this ongoing project will be used to ascertain if the novel glass is suitable for potential applications.
