Abstract

In this paper, elastoplastic post-buckling behavior of cylindrical tubes under axial compression is studied by using finite element method. In our study, the effects of tube geometries and strain hardening characteristics on high strain concentrations in circumferential direction εθ which arise at the vertex of outward wrinkles are investigated. It is found that the maximum value of εθ depends on the thickness-to-radius ratio t/R and the nondimentional hardening coefficient Eh/E, and independent of the length-to-radius ratio L/R. In addition, in order to evaluate the maximum strain εθ,max, the effects of tube geometries and strain hardening characteristics on the deformed shapes of folding wrinkles are also discussed.
