By introducing the $$C^{2}$$ continuous hexahedral element, the free vibration finite element analysis of the nanobeam and nanoplate structures is reported based on the second strain gradient (SSG) theory and three-dimensional elasticity model.

Frank network of dislocations within Mindlin’s second strain gradient theory of elasticity
International Journal of Mechanical Sciences, 2019A special configuration of dislocation networks consisting of a honeycomb-shaped grid of dislocation lines, which is referred to as Frank network, has not thus far been investigated in the context of any higher-order theories of elasticity.

Inverse Hooke's law and complementary strain energy in coupled strain gradient elasticity [PDF]
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2021 The inverse Hooke's law and complementary strain energy density has been examined in the context of the theory of coupled gradient elasticity for second gradient materials. To this end, it was assumed that the potential energy density is a quadratic form

Abstract In the context of Mindlin’s second strain gradient theory, a homogenization scheme for the determination of the effective overall properties of particulate composites with periodic microstructure is developed in this paper. This homogenization method is based on the direct application of an equivalent inclusion method adapted to second ...

Approaching second-strain gradient elasticity with soft X-rays diffraction
, 2022 It is well established that downsizing mechanical structures make their surface-over-volume ratio much larger than for usual objects, so that their ability to interact with their environment is significantly augmented. This has been particularly used in the development of cantilever sensors, where a surface energy change on one side induces the ...

In addition to enhancement of the results near the point of application of a concentrated load in the vicinity of nano-size defects, capturing surface effects in small structures, in the framework of second strain gradient elasticity is of particular interest. In this framework, sixteen additional material constants are revealed, incorporating the role
