| Abstract: | In this paper numerical method was used to study the postbuckling behaviors of Timoshenko beams with initial imperfection. The effect of initial imperfection on the postbuckling behaviors, the interaction between postbuckling and flexural wave and coupling of axial and transverse deformation were key issues in the study. |
