A SIMPLIFIED COMPUTATIONAL MODEL FOR MICROPLATES BASED ON A MODIFIED COUPLE STRESS THEORY
摘要
A novel simplified computational model (SCM) is developed for couple stress microplates by using a third-order deformation plate theory and by assuming the rotation about the z-axis is zero in the modified couple stress theory. 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.
