In this paper, by using adequate stress-strain relationship, mesh, boundary condition and loading condition, the finite element ANSYS was used to analyze the response for circular tubes subjected to pure bending creep or pure bending relaxation. Experimental data tested by Pan et al. [1] for SUS304 stainless steel tubes were compared with the ANSYS analysis. The response include the moment-curvature and ovalization - curvature relationships for the preloading pure bending stage, curvature-time and ovalization-time for preloading pure bending and subsequent pure bending creep stages and moment-time and ovalization-time for preloading pure bending and subsequent pure bending relaxation stages. It has been shown that the analysis is in good agreement with the experimental data.
