【Abstract】 This paper presents the application of the finite element incremental perturbation method basing on Koiter’s general theory of stability to analyse the buckling strength of thin plates with dimple imperfections. The paper does give a systematic reserch upon the effect of dimple imperfections on the postbuckling strength of thin plates.更多还原
