In this paper, a size-dependent Timoshenko beam is developed on the basis of the couple stress theory. The couple stress theory is a non-classic continuum theory capable of capturing the small-scale size effects on the mechanical behavior of structures, while the classical continuum theory is unable

A microscale vibration analysis of micro-plates is developed based on a modified couple stress theory. The presence of the length scale parameter in this theory enables us to describe the size effect in microstructures. A variational approach based on Hamilton's principle is employed to obtain the g
Dynamic stability of microbeams made of functionally graded materials (FGMs) is investigated in this paper based on the modified couple stress theory and Timoshenko beam theory. This non-classical Timoshenko beam model contains a material length scale parameter and can interpret the size effect. The
The problem of the pure bending of a circular cylinder is solved within the linear couple-stress theory. The solution is obtained by correcting the classical solution with a solution in plane strain within the section. A generalized formula is thus derived for the bending inertia of a circular cross
