Nonlocal elasticity in nanobeams: the stress-driven integral model

Nonlocal elastic models have attracted an increasing amount of attention in the past years, due to the promising feature of providing a viable simulation for scale effects in nano-structures and especially in nano-beams designed for use as actuators or sensors. In adapting Eringen’s nonlocal model of elasticity to flexure of nano-beams, the bending field is expressed as convolution between the elastic curvature field and an averaging kernel....
