文摘

Thermal postbuckling of temperature-dependent FG-CNTRC beams is investigated. Various possible imperfection is considered by using a generic imperfection model. Sensitivity of thermal postbuckling behaviour to various imperfections is discussed. Thermal postbuckling path is sensitive to imperfection shape, location, and amplitude. Imperfect FG-CNTRC beams do not exhibit bifurcation-type thermal postbuckling.
