Parametric Study of Axisymmetric Circular-Glass Plates

Thin-glass window-glass plates undergo deflections 10 times their thickness before they fail by brittle fracture and, hence, a complete-elastic large-deflection analysis of glass plates was found to be necessary to assess the behavior and design of thin-glass plates.

Description
Summary:Thin-glass window-glass plates undergo deflections 10 times their thickness before they fail by brittle fracture and, hence, a complete-elastic large-deflection analysis of glass plates was found to be necessary to assess the behavior and design of thin-glass plates. The von Karman nonlinear-plate theory has been found to be applicable for such analysis. Here, the analysis of axisymmetric-circular plates subjected to uniformly distributed pressures is made using an iterative procedure. As deflections become large, the maximum stress in the plate is no longer at the center of the plate. The governing differential equations are nondimensionalized, and in the nondimensional maximum-deflection, stresses are presented in terms of nondimensional-applied pressure in graphical as well as tabular forms.
