The stresses induced by large deflections have been derived for the case of a clamped flat circular plate that is uniformly loaded to its failure point. The analysis is based on an assumed deflection contour and is, therefore, an approximation. However, the boundary conditions are satisfied and the relatively uncomplicated expressions for membrane and bending stress yield critical impulse values which may be scaled successfully to apply to plates of other dimensions. The expressions for the principal stresses in a clamped flat circular plate are analyzed.
