Title (EN) THERMALLY STRENGTHENED GLASS SHEETS HAVING CHARACTERISTIC MEMBRANE STRESS HOMOGENEITY
(FR) FEUILLES DE VERRE RENFORCÉES PAR VOIE THERMIQUE PRÉSENTANT UNE HOMOGÉNÉITÉ DE CONTRAINTE DE MEMBRANE CARACTÉRISTIQUE
Abstract:
(EN) A glass sheet thermally strengthened such that at the first major surface is under compressive stress; the sheet having an a characteristic 2D autocorrelation matrix c(x,y) given by c(x,y)=F-1(F(g)•Fˆ(g)) where F is a 2D Fourier transform and ˆ represents a complex conjugate operation and g is a high pass filtered data array given by g(x,y)=F-1 (F(f)(1-F(h)) where h is a spatial 2D low pass filter array and f is a square data array of Shear 0 and Shear 45 data, taken over an area away from any birefringence edge effects on the sheet, wherein an autocorrelation peak maximum width of the matrix c(x,y) at 40% of peak height, for the c(x,y) matrices from both the Shear 0 and Shear 45 data, is between 1 and 5 mm.
(FR) La présente invention concerne une feuille de verre renforcée par voie thermique de façon que la première surface principale soit sous une contrainte de compression. La feuille comprend une matrice d'autocorrélation 2D caractéristique c(x,y) donnée par c(x,y)=F -1 (F(g)•Fˆ(g)) F est une transformée de Fourier 2D et ˆ représente une opération de conjuguée complexe et g est une matrice de données filtrée passe-haut donnée par g(x,y)=F -1 (F(f)(1-F(h)) h est une matrice de filtres passe-bas 2D spatiaux et f est une matrice de données au carré de données de cisaillement 0 et de cisaillement 45, prise sur une zone éloignée d'un quelconque effet de bord de biréfringence sur la feuille, une largeur maximale de pic d'auto-corrélation de la matrice c(x,y) à 40 % de la hauteur du pic, pour les matrices c(x,y) provenant des données de cisaillement 0 et de cisaillement 45, étant comprise entre 1 et 5 mm.
