COMPARISON OF GLASSY MATERIALS MECHANICAL PARAMETERS IN TORSION AND BENDING TEST MODE

Abstract

The mechanical properties of chalcogenide glasses in general are important given their application in protective coatings, infrared optics, sensors and other devices. The mechanical properties of glasses and glass-ceramics were studied utilizing Vickers hardness, in torsion mode, which requires a complete separate measurement setup, or by bending, used to determine the viscoelastic properties of polymers and composites. All this investigation shows a low mechanical property what limit the application of chalcogenide glasses [1]. We made comparison between bending and torsion investigations of chalcogenide glass mechanical properties.
