Static and Dynamic Analysis of Strain Gradient Planar Trusses

Buildings
This paper examines the static and dynamic responses of strain gradient planar trusses. Classical elasticity (CE) theory lacks a material microstructural length parameter in its governing equations, making it insufficient to capture size-dependent ...

Nanomechanics of a screw dislocation in a functionally graded material using the theory of gradient elasticity

Journal of the Mechanical Behavior of Materials, 2013
The modest aim of this short article is to provide some new results for a screw dislocation in a functionally graded material within the theory of gradient elasticity. These results, based on a displacement formulation and the Fourier transform technique,

The ab-initio aided strain gradient elasticity theory: a new concept for fracture nanomechanics

Fracture and Structural Integrity, 2019
When the width of cracked nanocomponents made of brittle or quasi-brittle materials is less than approximately , the size of the - dominance zone becomes smaller than and comparable to the fracture process zone ( ).

A size-dependent model for predicting the mechanical behaviors of adhesively bonded layered structures based on strain gradient elasticity

, 2021
As adhesively bonded layered devices scale down, micro-scale adhesive layers become common and play a key role in the overall performance of micro devices.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Buckling analysis of nonuniform nonlocal strain gradient beams using generalized differential quadrature method

Alexandria Engineering Journal, 2018
Recently, it was shown that the length scales presented in nonlocal elasticity and strain gradient theory each describe a different physical and material properties of structures at small scales.

Axial and Torsional Free Vibrations of Elastic Nano-Beams by Stress-Driven Two-Phase Elasticity [PDF]

Journal of Applied and Computational Mechanics, 2019
Size-dependent longitudinal and torsional vibrations of nano-beams are examined by two-phase mixture integral elasticity. A new and efficient elastodynamic model is conceived by convexly combining the local phase with strain- and stress-driven purely ...

Strong Ellipticity and Infinitesimal Stability within Nth-Order Gradient Elasticity

Mathematics, 2023
We formulate a series of strong ellipticity inequalities for equilibrium equations of the gradient elasticity up to the Nth order. Within this model of a continuum, there exists a deformation energy introduced as an objective function of deformation ...

Atomic scale lattice distortions and domain wall profiles

, 2003
We present an atomic scale theory of lattice distortions using strain related variables and their constraint equations. Our approach connects constrained {\it atomic length} scale variations to {\it continuum} elasticity and describes elasticity at ...

Verification of strain gradient elasticity computation by analytical solutions

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2021
As there are different computational methods for simulating problems in generalized mechanics, we present simple applications and their closed‐form solutions for verifying a numerical implementation.
