Краткое описание

In this paper, a 21-degree of freedom three-node triangular element is introduced for buckling analysis of the laminated composite Mindlin plate model based on new modified couple-stress theory. The present element can satisfy C1 weakcontinuity conditions and C0 continuity conditions. Numerical examples have been used to illustrate how the present element not only captures the scale effects of microstructure with far more complex boundary conditions than analytical methods, but also predicts the critical buckling loads. Note that numerical results of the present element can coincide with analytical results in the case of simply supported rectangular plates.
