Zusammenfassung
Thermally tempered glass will fragmentize completely into many pieces, if the equilibrated residual stress state within the glass plate is disturbed sufficiently and if the elastic strain energy in the glass is large enough [1], [2], [3], the fragmentation is the direct consequence of the elastic strain energy that is stored inside the material due to the residual stress state [4],[5]. The fragment size depends on the amount of the stored energy. Small fragments are caused by highly stored strain energy due to the high residual stress state originating from the extremely rapid cooling.
