When the thickness of metallic cantilever beams reduces to the order of micron, a strong size effect of mechanical behavior has been found. In order to explain the size effect in a micro-cantilever beam, the couple-stress theory (Fleck and Hutchinson, J Mech Phys Solids 41:1825–1857, 1993) and the C-W strain gradient theory (Chen and Wang, Acta Mater 48:3997–4005, 2000) are used with the help of the Bernoulli–Euler beam model. The cantilever beam is considered as the linear elastic and rigid… CONTINUE READING
