Modelling size-dependent bending, buckling and vibrations of 2D triangular lattices by strain gradient elasticity models: applications to sandwich beams and auxetics

TL;DR: In this paper, a generalized Bernoulli-Euler and Timoshenko sandwich beam models are derived by means of a computational homogenization technique and two additional length scale parameters involved in the models are validated by matching the lattice response in benchmark problems for static bending and free vibrations calibrating the strain energy and inertia gradient parameters, respectively.
Journal ArticleDOI

Variational formulations, model comparisons and numerical methods for Euler–Bernoulli micro- and nano-beam models:

TL;DR: In this paper, variational formulations and governing equations with boundary conditions are derived for a pair of Euler-Bernoulli beam bending models following a simplified version of Mindlin's...

Isogeometric analysis for sixth-order boundary value problems of gradient-elastic Kirchhoff plates

TL;DR: In this paper, the authors formulated the sixth-order boundary value problems of a one-parameter gradient-elastic Kirchhoff plate model in a weak form within an H 3 Sobolev space setting with the corresponding equilibrium equations and general boundary conditions.
Journal ArticleDOI

Variational formulation and isogeometric analysis for fourth-order boundary value problems of gradient-elastic bar and plane strain/stress problems

TL;DR: In this paper, the authors formulated the fourth-order boundary value problems of one parameter gradient-elastic bar and plane strain/stress models in a variational form within an H 2 Sobolev space setting.

A posteriori error estimates for the Morley plate bending element

TL;DR: A local a posteriori error indicator for the well known Morley element for the Kirchhoff plate bending problem is presented and is proven to be both reliable and efficient.
