“…The number of elements depends on the required accuracy and also on the user capability to experimentally determine the model parameters. For example, some authors used a GMM with 3 elements [10] when others retained 6 elements [3,5].…”

“…Around the glass transition temperature, glass is characterized by a viscoelastic behavior. Rheological models made up of springs and dashpots are often used in the literature to represent glass viscoelastic behavior [3][4][5][6][7], notably during the forming process [2,[8][9][10]. The Maxwell model is used in [2,6,7] because it is easy to be implemented and provides satisfactory results.…”

“…In the recent years, with the availability of finite element (FE) computer packages, advanced constitutive models and material parameter characterisation techniques were introduced to take into account temperature-dependent viscoelasticity, structural volume relaxation and temperature history of the tempering process. 7 The models described above and other models reported in the literature provide useful insight into the residual stresses in tempered glass. However, there is no validated model among the glass research/engineering community to incorporate the effect of residual stress.…”

“…The specific volume of glass which is required for modelling the residual stress depends on both thermal vibration and microstructural rearrangement. One of the simplest theories used in the literature was the instant freeze model of Bartenev (as quoted in Nielsen et al 7 ), where an instance change from being a liquid that has no ability to carry stresses to a fully elastic rigid solid at the glass transition temperature. The works of Narayanaswamy 8,9 considered the structural relaxation which accounts for the effects of the rate of cooling on the properties of glass.…”
