Point Defect in a Nonlocal Elastic Medium
Journal of Mathematical Sciences, 2001A nonlinear elastic body is studied in the framework of the model proposed by \textit{A.C.~Eringen} [Int. J. Engin. Sci. 10, No.~5, 425--435 (1972; Zbl 0241.73005)]. Besides the nonlinear Hooke law is replaced by the integral correlation \[ t(x) = \int\limits_V \alpha(| x'-x| ,\tau)\sigma(x')\,dv(x'), \] where \(\sigma(\cdot)\) is a linear strain ...

Nonlocal elasticity theory of polymeric liquid crystals
Physical Review A, 1990We construct a nonlocal theory of elasticity for a nematic polymer composed of rigid or semiflexible molecules. We then introduce a mean-field theory for the calculation of wave-vector-dependent elastic moduli. Because the length of the molecules can be comparable to observable elastic distortions, the wave-vector dependence of the Frank moduli, i.e ...

The influences of considering coupled axial-flexural vibrations on efficiency of cantilever mass nanosensors, modeled by Rayleigh and Timoshenko beam theories, are investigated in the frame work of a paradox-free nonlocal theory, i.e.

A strain-difference based nonlocal elasticity model devised by the authors elsewhere (Polizzotto et al., Int. J. Solids Struct. 25 (2006) 308–333) is applied to small-scale homogeneous beam models in bending under static loads in the purpose to describe ...

Edge dislocation in nonlocal elasticity
International Journal of Engineering Science, 1977Abstract The solution is presented for the problem of straight edge dislocation in nonlocal elasticity. The stress field and elastic energy are calculated. Classical singularities in the expressions of the stress field and stored energy are found not present in the nonlocal model. An estimate is made for the critical shear stress which will produce a

Lattice-Based Nonlocal Elastic Structural Models
2021This chapter is devoted to lattice-based nonlocal approaches in relation with elastic microstructured elements. Nonlocal continuous approaches are shown to be relevant for capturing length scale effects in discrete structural mechanics models. The chapter contains three complementary parts.

The theory of nonlocal elasticity is developed. Balance laws, jump conditions and the second law of thermodynamics are given. By means of axioms of nonlocality, objectivity and the entropy inequality, the constitutive equations are derived for nonlocal elastic solids.
