Finite-Element Analysis of Polyhedra under Point and Line Forces in Second-Strain Gradient Elasticity

Journal of Engineering Mechanics - ASCE, 2017
AbstractIn this paper, a finite-element implementation of linear second-strain gradient elasticity is introduced based on a Hellinger-Reissner variational principle in order to use standard finite-element methods. Displacement boundary conditions are applied to one or more vertices of different polyhedrons.

Second strain gradient elasticity of nano-objects

Journal of the Mechanics and Physics of Solids, 2016
Mindlin's second strain gradient continuum theory for isotropic linear elastic materials is used to model two different kinds of size-dependent surface effects observed in the mechanical behaviour of nano-objects. First, the existence of an initial higher order stress represented by Mindlin's cohesion parameter, b0, makes it possible to account for the

The Kirsch problem in second strain gradient elasticity

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
The Kirsch problem, namely the problem of an infinite plane with a circular hole under uniaxial tension, is one of the cornerstone problems in elasticity. The Kirsch problem is rooted in classical elasticity theory, which cannot explain the size effects.

On admissible external loadings within the first and second strain gradient elasticity

Mathematics and Mechanics of Solids
Recent extended applications of higher-order models of continuum mechanics as strain gradient elasticity and plasticity result in a certain extension of possible external loadings.
