Abstract

In this paper, the elastoplastic deformation behaviors of cylindrical tube subjected to statically axial compression are studied by using finite element method (FEM). The effects of tube geometries and strain hardening characteristics of the material on the deformation behaviors are investigated. Generally, although it is recognized that the deformation situation along the circumferential direction is dependent on the thickness ratio (R/t), it is found that the deformation is also greatly dependent on the edge constraint. The deformation mode along; the circumferential direction also affects the deformation mode along the axis-direction. A method to control the deformation mode, such as adding a disk in tube center, is proposed to maintain the deformation keeping in an axi-symmetric mode.
