Geomechanical Model Test and Energy Mechanism Analysis of Zonal Disintegration in Deep Surrounding Rock

open access: yesGeosciences, 2018
With the decreasing of shallow resources, underground roadways of resources exploitation have reached into deep rock mass with high geostress. A series of new failure phenomena such as zonal disintegration phenomenon were discovered in deep surrounding ...

A New Method of Fatigue Life Prediction for Notched Specimen

open access: yesJournal of Aeronautical Materials, 2017
The simulations of the notched specimens under multiaxial loading were conducted by finite element method. The simulation results show that the stress gradient increases with the decrease in notch radius for the same strain path.

Cellular Orientation Is Guided by Strain Gradients [PDF]

open access: yesIntegrative Biology, 2016
The strain-induced reorientation response of cyclically stretched cells has been well characterized in uniform strain fields. In the present study, we comprehensively analyse the behaviour of human fibroblasts subjected to a highly non-uniform strain field within a polymethylsiloxane microdevice.

Nonlocal-Strain-Gradient-Based Anisotropic Elastic Shell Model for Vibrational Analysis of Single-Walled Carbon Nanotubes

open access: yesC
In this study, a new anisotropic elastic shell model with a nonlocal strain gradient is developed to investigate the vibrations of simply supported single-walled carbon nanotubes (SWCNTs).

On Representing Strain Gradient Elastic Solutions of Boundary Value Problems by Encompassing the Classical Elastic Solution

open access: yesMathematics, 2022
The present work aims to primarily provide a general representation of the solution of the simplified elastostatics version of Mindlin’s Form II first-strain gradient elastic theory, which converges to the solution of the corresponding classical elastic ...

Strain-gradient-induced switching of nanoscale domains in free-standing ultrathin films [PDF]

open access: yes, 2014
We report first-principle atomistic simulations on the effect of local strain gradients on the nanoscale domain morphology of free-standing PbTiO$_3$ ultrathin films. First, the ferroelectric properties of free films at the atomic level are reviewed. For

Strain gradient and electric field gradient effects in piezoelectric cantilever beams

open access: yesJournal of the Mechanical Behavior of Materials, 2015
A piezoelectric beam model with strain gradient and electric gradient effects is proposed. An energy variational principle with strain, strain gradient, electric field, and electric field gradient considered as independent variables is postulated to ...

Numerical Study of Microbeam with Geometric Discontinuity Under Electrostatic Load using Strain Gradient Theory [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2020
In this work, the pull in analysis of microbeam with geometric discontinuity for two different boundary conditions has been investigated. Boundary conditions are considered as Clamped-Free (CF) and Clamped-Clamped (CC).
