Abstract: A process to obtain a glazing which withstands a dynamic impact when it is installed in a structure, such as a bird strike for a glazing installed in an aircraft, the glazing including at least one glass sheet, the process including with the aid of a finite-element numerical model of the glazing installed in the structure and subjected to the impact, using a law of behavior of the constituent material of each glass sheet, the maximum stress envelope on each glass sheet of the glazing is calculated; and for each glass sheet of the glazing, the maximum stress envelope is compared to the fracture stress of the glass sheet obtained according to an experimental method for determining the fracture stress of a glass sheet selected as a function of the type of impact.

Abstract: A laminated glazing includes at least a first glass sheet of soda-lime-silica type, a second glass sheet which is thinner than the first glass sheet and a polymeric interlayer located between the two glass sheets, in which the second glass sheet is a glass of aluminosilicate type including the following oxides within the ranges of contents by weight defined below: SiO2 between 60.00 and 68.00%; Al2O3 between 2.80 and 7.80%; Na2O between 10.00 and 15.80%; MgO between 4.90 and 10.10%; K2O between 4.80 and 9.70%; B2O3 between 0 and 3.20%; and CaO between 0 and 1.00%.
