Elasto-Plastic Finite Displacement Analysis of Thin-Walled Shells
Fabricated or manufactured steel pipes are well known as typical thin-walled shell structures used in civil engineering. These steel pipes are widely used as column members in most structures since the cylindrical shell retains an effective shape under axial loading and under external or internal pressure. An isoparametric shell element is useful for the analysis of such shell structures because the curved shape of the shells can be approximated adequately by this method. An elasto-plastic finite displacement analysis program, Nonlinear Analysis of Shell Structures (NASHEL), has been developed to analyze the structural characteristics of these thin-walled structures by use of the isoparametric shell element. In this report, the calculation procedures of some of the points of the NASHEL program are summarized and the adaptability of the program to large displacement problems is investigated through the use of several numerical examples.
