Abstract
In this study the plastic buckling analysis of a circular cylinder und er axial compression is carried out considering plastic compressibilit y. For the stability analysis, the linearized finite element equation is derived and the general elastic-plastic constitutive equation is fo rmulated. The Drucker-Prager plastic potential is used to describe the plastic compressible yielding and the strength-differential effect. T he influence of plastic compressibility on the buckling load is invest igated for a circular cylinder.
