Free vibrations of stepped nano-beams

Abstract: Free vibrations of beams and rods made of nano-materials are investigated. It is assumed that the dimensions of cross sections of nano-beams are piecewise constant and that the beams are weakened with cracks. It is expected that the vibrational behaviour of the nano-material can be described within the non-local theory of elasticity and that the crack induces additional local compliance. The latter is coupled with the stress intensity coefficient at the crack tip.

“…Eringen (2002) introduced also differential approach to the specific class of kernel functions which admitted to transform the constitutive equations into the form of differential equations. Following Eringen (2002), Reddy (2007aReddy ( , 2007b, Lellep and Lenbaum (2018), we shall use the constitutive equations for the bending moment M as…”
