More precisely, an edge-cracked nanobeam is examined. Such a cracked nanobeam is modelled by using a modification of the classical cracked-beam theory, consisting in dividing the nanobeam into two beam segments connected through a massless elastic rotational spring located at the cracked cross section. The deflection is obtained for different values of both relative crack depth and crack orientation. Further, the dimensionless transversal displacement along the beam length is determined considering a crack length equal to half of the beam height and characterised by different orientations. © 2023 The Authors.

1. Introduction Nanostructures, such as nanobeams, nanorings, single-curved nanoshells and double-curved nanoshells, are structures with one or more than one size falling in the nanometer scale range. They can be used alone or in conjunction with a matrix to be reinforced, in the latter case forming a nanocomposite. When used alone, the main fields of
