<p>According to the method of the invention for manufacturing laminated glazing such that it resists predetermined stresses, reference laminated glazing is identified which resists the predetermined stresses and which comprises at least one substrate and an insert having the same chemical compositions as the laminated glazing to be manufactured; the tear strength (J) of the laminated glazing insert, as well as the thickness of the insert (e) and the thickness of the substrate (e) of the reference laminated glazing is then determined; then, using a graph (C) representing the minimum tear resistance of the insert (J) required for any given laminated glazing, comprising at least one substrate and an insert having the same chemical composition as the laminated glazing to be manufactured, and resisting the predetermined stresses, on the basis of the thickness of the insert (e) and/or on the thickness of the substrate (e), a combination of optimal values (e, e) is deduced for the thickness of the insert and the thickness of the substrate; the laminated glazing is then sized with an insert thickness (e) and a substrate thickness (e) greater than or equal to the optimal values (e, e).</p> |
