The present paper examines the large deflections of a clamped circulate thin plate for pressure sensor applications and establishes a simple solution using the singular perturbation technique. The perturbation solution for the slope of the lateral deflection is in a closed form in terms of the load-induced radial stress resultant. The nonlinearity has a strong stiffened effect. The nondimensional load-induced stress resultants are functions of the nondimensional initial stress resultant, lateral load, and Poisson’s ratio.
