The motivation for this work is the need for more extended guidelines considering structural design of glass structures. Realistic models predicting the strength of bolted connections are a step towards improvement of such guidelines. Improvement of guidelines for bolted connections require in-depth knowledge of the residual stresses in toughened glass near holes and edges where the total stress state is a combination of contact stresses and residual stresses. The present paper, presenting the derivation and results for a model predicting the residual stresses in a glass plate far from edges and holes, is a step towards such a model. The model is based on the Instant Freeze concept with a few modifications. Current work, using a partial differential equation approach for the modeling and state-of-the-art in modeling residual stresses in glass is briefly presented, and a short description of the toughening process is given.
