PLASTIC BUCKLING PRESSURE FOR SPHERICAL SHELLS

Abstract

A solution for the plastic axisymmetric buckling of thinwalled spheres under hydrostatic pressure is derived. The theory accounts for strainhardening of material and changes of Poisson's ratio in the plastic range. The plasticity reduction factor is expressed in terms of tangent and secant moduli and new concepts of tangent and secant Poisson's ratios. For typical engineering materials there is little difference between the results obtained from this solution and the earlier ones obtained from the solutions of Bijlaard and Gerard. (Author)
