Linear and Nonlinear Deflection of a Circular Plate

A circular plate of radius r and thickness t with clamped edges is subjected to a uniform load q that covers the entire plate. The plate material has a Poisson's ratio of 0.3 and a Young's modulus of E. The central deflection parameter, $W=\frac{w}{t}$, is plotted against the load parameter, $Q=\frac{q r^4}{E t^4}$, in Figure (2.7) and found to agree with the analytical solution presented in [270]. The magnitude of the central deflection was significantly reduced when large deflection effects were included.
