Nonlocal continuum mechanics formulation for axial, flexural, shear and contraction coupled wave propagation in single walled carbon nanotubes
Full text linkImperfections in non-local elasticity
No full textIn non-local elasticity the stress at a reference point depends not only on the strain at this point but also on strains at all other points of the body. Various type imperfections are investigated in the frame-work of this theory. The non-local stresses have no singularities in contrat to the corresponding classical results which yield infinite stresses and divergent energies and cannot describe the situation in the strongly distorted region in the vicinity of the defect

Scaling Laws for Properties of Materials with Imperfect Interfaces
No full textSurfaces/interfaces have a profound effect on the properties of nanostructured and heterogeneous materials due to the large ratio of Surface/interface atoms to the bulk. Imperfect interfaces widely exist in conventional composites and nanostructured materials. This paper shows that when imperfect interfacial bonding conditions are taken into account, some intrinsic length scales emerge. Thus, in contrast to the perfectly-bonded interfaces, the effective properties of heterogeneous materials containing inhomogeneities with imperfect interfaces become dependent upon the, size of the inhomogeneities. This size-dependence is shown to be captured by simple scaling laws depending upon the type of the interface imperfection.Engineering, CivilEngineering, MechanicalMathematics, AppliedEICPCI-S(ISTP)
