Nonlocal Elasticity Theory for the Mechanical Behavior of Protein Microtubules

Physical Mesomechanics, 2021
В работе представлена теория балок Редди с нелокальными дифференциальными определяющими уравнениями Эрингена, а также уравнения движения белковых микротрубочек в терминах обобщенных смещений. Приведено аналитическое решение изгиба белковых микротрубочек для выявления влияния нелокального поведения на отклонения.

Saint-Venant Principle on Problems of Nonlocal Elasticity Theory

Herald of the Bauman Moscow State Technical University. Series Natural Sciences, 2023
Simulating the modern structural materials requires introduction of a model that takes into account structural features at the micro-level. The Eringen’s nonlocal elasticity theory model could be referred to such models.

A review on stress-driven nonlocal elasticity theory

, 2021
The behavior of materials at the nanoscale cannot be studied by classical theories. Accordingly, new theories have been developed to predict the behavior of materials at the nanoscale; some of them are nonlocal elasticity, strain gradient theory, couple stress theory, and surface effect theory.

Essential Concepts from Nonlocal Elasticity Theory

Springer Tracts in Mechanical Engineering, 2019
Nonlocal elasticity theory is a convenient methodology for considering the small-scale effects that are exhibited by nanoscopic structures. In recent decades, the use of nonlocal elasticity theory in mechanical modelling of these structures has seen an inflationary development.

Size-dependent vibration of functionally graded rotating nanobeams with different boundary conditions based on nonlocal elasticity theory

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2021
The free vibration of rotating functionally graded nanobeams under different boundary conditions is studied based on nonlocal elasticity theory within the framework of Euler-Bernoulli and Timoshenko beam theories.

A meshless collocation method for band structure simulation of nanoscale phononic crystals based on nonlocal elasticity theory

Journal of Computational Physics, 2020
In this paper, the band structures of nanoscale phononic crystals based on the nonlocal elasticity theory are calculated by using a meshfree local radial basis function collocation method (LRBFCM). The direct method is applied to enhance the stability of
