ELASTIC-PLASTIC DISCRETE-ELEMENT ANALYSIS OF ASYMMETRICALLY-LOADED SHELLS OF REVOLUTION.
Abstract
A discrete-element matrix-displacement method is developed for the elastic-plastic small-deflection analysis of meridionally-curved shells of revolution subjected to asymmetric loading. Fourier series is used to describe the circumferential variations of loads, pressures, displacements, stresses, etc. The 'initial strain' approach in conjunction with the Mises-Hencky yield criterion and the plastic flow rule in accordance with the theory of plastic potential is used to determine the effects of plasticity. This method has been implemented as a digital computer program, and the computer solutions are compared to experimental results for two example shells. (Author)
