Abstract

This paper presents the nonlinear static bending analysis of variable thickness microplates by using the finite element method and modified couple stress. The present theory and mathematical model are confirmed by comparing the numerical data with those of open literatures. A parameter study is carried out to investigate the mechanical behavior of the structure, especially, the effect of nonlinearlity. The computed data can be used as a good reference in the use and design of these types of structures in engineering practice.
