A reduced model for determining the stresses of a glass with various supports subjected to dynamic impact load is developed. The model is compared to a full dynamic finite element model. The aim is to develop a model that may be integrated into glass design programs for strength design of glass structures. The model is applicable to centrally and excentrically applied impact and to glass of various support conditions. It is demonstrated that the model performs well for four-sided supported glass panes and an impact applied at the centre of the glass pane. The applicability to small or medium sized glass panes is shown through a parametric investigation. For large glass panes, especially at smaller glass thicknesses, it is suggested that the geometrically nonlinear behaviour of the glass pane is integrated into the model.
