Book excerpt: "Laminated glazing has been a popular form of window glazing in recent years and is found to be effective during extreme weather conditions like hurricane. Laminated glass is composed of two glass layers with a polymer as an interlayer. The main objective of this work involves studying the stress response, failure and damage analysis of rectangular laminated architectural glazing against combined wind and windborne debris impact. Here both small-hard (like roof gravel) and large-soft (like timber) windborne debris are considered. The stress response of the rectangular laminated architectural glazing was modeled using the finite element code ABAQUS. The effect of geometric and material properties of glass and PVB on the stress response is studied to find an optimum configuration with impact resistance as criteria. Also, the stress distribution through the thickness of glazing is studied. The cumulative probability of failure of the inner ply of the laminated glazing is studied by using a mechanics based analytical model. Based on cumulative damage theory, a two-parameter Weibull distribution is used to predict the existence of flaws capable of causing failure in the inner glass ply. The stresses in the laminate are determined from finite element analysis. Effects of combined wind and debris impact and geometry of glazing on failure probability is studied. The fracture of the laminated glazing has been studied in an average sense using Continuum Damage Mechanics (CDM). An anisotropic elastic damage tensor with a linear damage evolution has been chosen to model the damage through the glass. This model is implemented in finite element code to study the damage. A parametric study involving the geometry of glazing is used to study the damage. The damage patterns and zone sizes are predicted with this model"--Abstract, leaf iv.
