Plastic limit analysis of cylindrically orthotropic circular plates

摘要

The plastic limit analysis of cylindrically orthotropic circular plates is developed using a piecewise linear orthotropic yield cri- terion. The yield criterion is a modification of an isotropic formulation that consists of a series of weighted piecewise linear components. The piecewise linear yield criterion enables and analytical solution for the plastic limit load of cylindrically orthotropic circular plates. Plastic limit analysis for both simply supported and clamped circular plates under uniformly distributed load are carried out.
