Abstract of: Experimental investigation into the fragment size of tempered glass
This work presents the relation between the fragment density and the permanent residual stress in fragmented tempered glasses of various thicknesses. Therefore, fracture tests were carried out on tempered glass plates and the fragments in observation fields of 50 mm × 50 mm were counted. The averag...

This work presents the relation between the fragment density and the permanent residual stress in fragmented tempered glasses of various thicknesses.

Furthermore, the average particle weight of 130 particles per specimen chosen by random was determined. The relation between the average particle weight and the measured residual stress is given.
