Abstract

Dynamic Relaxation (DR) finite-difference analyses incorporating the Ilyushin full-section and the Von Mises layered yield constitutive models are used to predict the full-range axisymmetric response of circular plates subjected to uniform normal pressure. By means of a comparison of the predicted responses for limiting values of slenderness and edge support conditions it is established that, compared to the Von Mises model, the Ilyushin model tends to produce an overstiff representation of the plate response. The deficiencies in the Ilyushin model are shown to be twofold: (1) an inability to predict accurately the first yield pressure, especially for slender plates, and (2) an inaccurate representation of the development of the stress couples in the post first yield regime. Despite these shortcomings it is, nevertheless, concluded that the pressure - deflection response predicted by the Ilyushin model is adequate for design purposes.
