PROCESS FOR MANUFACTURING A LAMINATED GLAZING |
摘要 |
A process for manufacturing a laminated glazing, in which a lamination interlayer is interposed between two substrates having a glass function, including: making a measurement of Young's modulus E on a sample of the interlayer, using a viscoanalyzer, by varying temperature and frequency while imposing a constant dynamic displacement; making a numerical treatment of curves obtained, using WLF (Williams-Landel-Ferry) equations, to establish a law E(f) governing behavior of a material constituting the interlayer sample at a given temperature; producing a numerical model based on a finite-element method in bending of a laminated glazing panel, wherein mechanical properties of the sample result from the preceding operations; comparing results of the numerical calculation with those obtained with analytical formulae in which participation of the interlayer in transferring shear in the laminated glazing is represented by a transfer coefficient ω; varying the transfer coefficient ω in the analytical formulae until results converge; and constructing a transfer function ω=f(E) by successive iterations. |
