Contact model for DEM simulation of compaction and sintering of all-solid-state battery electrodes

MethodsX, 2022
In this study, a discrete element method (DEM) that can simulate particle plastic deformation, sintering, and electrode compaction of all-solid-state batteries was developed.

Mode I crack tip fields: strain gradient plasticity theory versus J2 flow theory

, 2019
The mode I crack tip asymptotic response of a solid characterised by strain gradient plasticity is investigated. It is found that elastic strains dominate plastic strains near the crack tip, and thus the Cauchy stress and the strain state are given ...

Spatial repartition of local plastic processes in different creep regimes in a granular material [PDF]

, 2016
Granular packings under constant shear stress display below the Coulomb limit, a logarithmic creep dynamics. However the addition of small stress modulations induces a linear creep regime characterized by an effective viscous response.

Research on Quasi-Elastic–Plastic Optimization of Reinforced Concrete Frame–Shear Wall Structures

Buildings
Precise determination of structural elastic–plastic displacement and component states under rare earthquakes is crucial for structural design. This article proposes a quasi-elastic–plastic optimization method for reinforced concrete structures. First, an

Proppant embedment behavior and elastic–plastic embedding depth modeling of coal reservoirs under multi-stage loading

Meitan xuebao
To investigate the elasto-plastic embedment behavior of proppant during coalbed methane (CBM) production, a mechanical testing system equipped with a high-precision displacement sensor was used to design and conduct proppant-embedment tests under multi ...

Comparisons Between Pull-Out Behaviour of Various Hooked-End Fibres in Normal–High Strength Concretes

International Journal of Concrete Structures and Materials, 2019
In this paper an elastic–plastic response has been developed to predict the pull-out behaviour of various hooked end fibres embedded in normal–high strength concretes.

A New Unified Solution for Circular Opening considering Different Strength Criteria and the Postpeak Elastic Strain Form

Advances in Civil Engineering, 2020
The strength criterion is an extremely important basis for evaluating the stability of surrounding rock and optimizing the support pressure design. In this paper, nine different strength criteria are summarized and simplified based on the reasonable ...

Helical single-walled carbon nanotubes under mechanical and electrostatic loading

Carbon Trends, 2022
Here, we characterize the axial response of helical single-walled carbon nanotubes (HSWCNTs) to mechanical and electrostatic loads, separately. The study considers low-pitch (closed) and high-pitch (open) HSWCNTs of different number of turns in their ...

Critical earthquake response of elastic-plastic structures under near-fault ground motions (Part 2: Forward-directivity input)

Frontiers in Built Environment, 2015
The triple impulse input is used as a simplified version of the forward-directivity near-fault ground motion and a closed-form solution of the elastic-plastic response of a structure by this triple input is obtained.
