Analytical solutions are obtained for bending, free vibration, and buckling behaviors of couple stress microplates. Using the present model, a three-node triangular plate element is constructed, in which each node has only seven degrees of freedom. Numerical results of the SCM are compared with those calculated using the complete model (CM) and the original simplified model (SM) available in the literature. The results reveal that the present SCM shows a significant improvement in computational efficiency, while maintaining minimum loss in accuracy, compared with the CM. The computing time used in the CM is 2 −5.7 times that used in the SCM. PB Begell House LK https://www.dl.begellhouse.com/journals/61fd1b191cf7e96f,14250e200402b70b,1038485d108da647.html
