PARAMETRIC STUDY OF AXISYMMETRICAL CIRCULAR-GLASS PLATES

Thin-glass Window-glass plates undergo deflections 10 times their thic kness before they fail by brittle fracture and, hence, a complete-elas tic large-deflection analysis of glass plates was found to be necessar y to assess the behavior and design of thin-glass plates. The von Karm an nonlinear-plate theory has been found to be applicable for such ana lysis. 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 lo nger 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.
