Analysis of Damage in Laminated Architectural Glazing Subjected to Wind Loading and Windborne Debris Impact

Abstract

Wind loading and windborne debris (missile) impact are the two primary mechanisms that result in window glazing damage during hurricanes. Wind-borne debris is categorized into two types: small hard missiles; such as roof gravel; and large soft missiles representing lumber from wood-framed buildings. Laminated architectural glazing (LAG) may be used in buildings where impact resistance is needed. The glass plies in LAG undergo internal damage before total failure. The bulk of the published work on this topic either deals with the stress and dynamic analyses of undamaged LAG or the total failure of LAG. The pre-failure damage response of LAG due to the combination of wind loading and windborne debris impact is studied. A continuum damage mechanics (CDM) based constitutive model is developed and implemented via an axisymmetric finite element code to study the failure and damage behavior of laminated architectural glazing subjected to combined loading of wind and windborne debris impact. The effect of geometric and material properties on the damage pattern is studied parametrically

A Comparative Study on the Impact Behaviour of the Coated Glass Plates by FSDT and HSDT

“…In case of MG without the film, the damage is rapidly carried out from the impacted surface to the opposite surface, but in case of film CG with film, the film absorbs the impact and greatly prevents the damage. In addition, to protect the glass from foreign object impact, the presence of the film is very important rather than the thickness of the film, which is very similar to the role of intermediate PVB film of the laminated glass [7][8][9][10].…”
