摘要: In this paper, the static instability of a nanobeam with geometrical imperfections that is embedded in elastic foundation investigated. Size-dependent effect included nonlinear model. It argued nonlocal parameter may render initially unstable. Static response studied and condition for stated. The exact postbuckling solution both straight curved presented. shown bifurcation diagram initial sinusoidal configuration similar to its nearest buckling mode. results are verified pervious relevant works on nanobeams classical theory beams excellent agreement shown.
