<p>The invention relates to a method for manufacturing a laminated glazing element (1) such that the glazing element (1) withstands a predetermined load, wherein the element (1) comprises at least one substrate with a glass function (2, 4) and at least one intermediate polymer layer (3), said method including the steps of: obtaining the law of viscoelastic behaviour of the material constituting the intermediate layer (E(, T)) in the time and temperature ranges characteristic of the predetermined load; calculating the maximum value of at least one magnitude representing the load-bearing strength of the laminated glazing element (1) subjected to a predetermined load, using an analytical model in which the effect of the intermediate layer on the shear transfer is represented by a transfer coefficient and an equation that expresses the transfer coefficient in accordance with the Young's modulus of the intermediate layer, the load applied to the laminated glazing element, and the dimensions ( of the element (1); adjusting the dimensions ( of the element (1) such that the maximum calculated value of the magnitude representing the load-bearing strength of the element (1) is less than or equal to a maximum allowable value; and preparing and then assembling each substrate (2, 4) and each intermediate layer (3) with the adjusted dimensions (</p> |
