Dislocation core field. I. Modeling in anisotropic linear elasticity theory [PDF]

, 2011
Aside from the Volterra field, dislocations create a core field, which can be modeled in linear anisotropic elasticity theory with force and dislocation dipoles.

Model tests on piled raft subjected to lateral soil movement [PDF]

, 2017
Passive loadings due to lateral soil movement-induced activities are highly influencing the serviceability and safety of constructions. This research aims to investigate the influence of axial loads, sand density and the depth of moving soil on the ...

DEM study of particle scale and penetration rate on the installation mechanisms of screw piles in sand

, 2021
Screw piles are efficient anchors to sustain large uplift loads and can be installed with low noise or vibration. Screw piles dimensions are currently increasing, renewing research interest to reduce the installation requirements (torque and crowd or ...

Simulation Analysis on Pile-driving Process of Anti-flood Bionic Screw Pile

IOP Conference Series: Materials Science and Engineering, 2019
In order to reduce the dynamic energy consumption of pile-driving of the anti-flood screw piles, the unsmoothed surface is applied to the screw pile tip to form an anti-flood bionic screw pile.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Study on Bearing Mechanism of Steel Screw Pile

Buildings
In order to study the bearing mechanism of a steel screw pile (SSP), a 3D-FEM of “SSP-stratum” was established based on the large-scale general finite element analysis platform ABAQUS.

A link between microstructure evolution and macroscopic response in elasto-plasticity: formulation and numerical approximation of the higher-dimensional Continuum Dislocation Dynamics theory

, 2015
Micro-plasticity theories and models are suitable to explain and predict mechanical response of devices on length scales where the influence of the carrier of plastic deformation - the dislocations - cannot be neglected or completely averaged out.

The Peierls--Nabarro FE model in two-phase microstructures -- a comparison with atomistics

, 2020
This paper evaluates qualitatively as well as quantitatively the accuracy of a recently proposed Peierls--Nabarro Finite Element (PN-FE) model for dislocations by a direct comparison with an equivalent molecular statics simulation.

Effects of axial loads and soil density on pile group subjected to triangular soil movement [PDF]

, 2017
Laboratory tests have been carried out to investigate the response of 2x2 pile group subjected to triangular soil movement. The pile group was instrumented with displacement and tilting devices at the pile cap and strain gauges on two piles of the group.
