NUMERICAL APPROACH TO FINITE ELASTIC-PLASTIC DEFLECTIONS OF CIRCULAR PLATES

An elastic-plastic analysis of large deflections of axisymmetrically loaded circular plates is presented. Under the Kirchhoff-Love hypothesis, the incremental theory of plasticity together with the von Mises yield condition and the associated flow rule is adopted, and isotropic workhardening materials as well as elastic-perfectly plastic materials are treated. This is not an inherent limitation of the method. A numerical procedure with the finite difference approximation and the iteration technique is employed for the solution of the derived incremental basic equations of a two-point boundary value problem. Several results for various kinds of boundary condition and some values of plate thickness are given including the solutions of residual stress and strain for the first cycle of a loading-unloading process.
