Abstract
During their lifetime, glass panels are repetitively exposed to thermal stresses. These thermal stresses result from temperature differences within the panel, which most notably cause the edges of the panels to be stressed in tension. When these thermal stresses exceed the glass edge strength, failure will occur. In this study, the thermal stresses are calculated by finite element software on the basis of real climate data during a twenty year period. By means of these finite element analyses it is investigated whether or not the stresses in the glass exceed the edge strength of the glass, thereby causing its failure. For this purpose, the yearly maximum stresses are derived from the model. In addition, the entire thermal stress history has been taken into account to incorporate the effects of stress corrosion on the edge strength of the glass. From the study it is observed that the latter criterion may be more stringent than the former.
