Study of the Influence of Thermal Tempering on the Bending Behavior of the Silico Soda Lime Glass Material

Thermal tempering, glass, bending, stress, deflectionAbstract
In this contribution, we examine the mechanical behavior of tempered soda-lime-silica glass plates and show that improvements in performance can be achieved through the change of the structural and mechanical properties. Tests of thermal tempering by air jet have been performed on glass plates of different dimensions. Three-point bending tests have been conducted on nontempered and fully tempered float glass plates of four different sizes. A parametric study on the thickness of the plate and the conditions of tempering has been performed. The experimental results show that the thermal tempering improves the rupture resistance of glass plates. This experimental study has been supplemented by a numerical finite element simulation of the stress state which has shown a satisfactory comparison with experimental results. Finally, the numerical results show that the design deflection of tempered glass is much less than commonly assumed. Keywords: Thermal tempering, glass, bending, stress, deflectionVeröffentlicht
