Lattice defects in nonlocal elasticity
Physica B+C, 1979Abstract A general treatment of the properties of static lattice defects is given in nonlocal elasticity. The results are applied to calculate the elastic interaction and self-energy of dilatation centres. It is shown that the results are equivalent with the ones of discrete atomic model calculations.

Buckling loads of nano-beams in stress-driven nonlocal elasticity
Mechanics of Advanced Materials and Structures, 2020Size-dependent buckling of compressed Bernoulli-Euler nano-beams is investigated by stress-driven nonlocal continuum mechanics. The nonlocal elastic strain is obtained by convoluting the stress field with a suitable smoothing kernel.

Airy's Functions in Nonlocal Elasticity
Journal of Computational and Theoretical Nanoscience, 2011Nanostructured devices and materials, such as carbon nanotubes, Atomic Force Microscope, MEMS, etc. attract increasing attention in the scientific world. It has been realized that the classical elasticity is not capable to capture the mechanical behavior of them precisely.

Mechanics based design of structures and machines, 2020
Based on the first-order shear deformation (FSD) model and nonlocal elasticity theory, the simultaneous effects of shear and small scale on the nonlinear vibration behavior of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) beams are ...

Nonlocal Elastic-Damage Models
2014A theory of nonlocal isotropic damage for elastic quasi-brittle materials is presented under the assumption of isothermal conditions and small deformations. Key ingredients of this theory are a self-adjoint (regularization) operator which transforms a local field into a related nonlocal one while preserves uniform fields and a free energy which depends

Continuum theories describe a system in terms of few variables such as mass, temperature, voltage, and stress, which are highly suited for direct measurements of these variables. Their successes, expediency, and practicality, have been demonstrated and tested throughout the history of science through explaining and predicting diverse physical phenomena.
