Computational and Experimental Observation of Li-Ion Concentration Distribution and Diffusion-Induced Stress in Porous Battery Electrodes

A multiscale model of porous electrodes based on the Gibbs free energy is developed, in which the Li ion diffusion, diffusion-induced stress (DIS), and polydispersities of electrode particle sizes are considered. The relationships between the size polydispersities and the concentration profiles and DIS evolution are investigated numerically. Li ion distributions are verified by in situ observation of color changes in a commercial porous graphite electrode.

Harnessing Surface Wrinkling-Cracking Patterns for Tunable Optical Transmittance

Optical devices and systems with tunable optical transmittance have recently attracted great interest due to their wide range of applications. However, the reported methods of realizing tunable optical transmittance still suffer from complex fabrication processes, high cost, unstable materials or low tuning range. In this study, we report a simple, cheap, and highly effective approach to achieve large tuning range of optical transmittance through harnessing surface wrinkling-cracking patterns on PDMS films.

Experimental and numerical study of crack behaviour for capsule-based self-healing cementitious materials

Dear all,

Our group at Delft University is developing self-healing concrete for over a decade. Recently, they have published a combined experimental and modeling study related to designing these materials. More details are available at https://www.researchgate.net/publication/319542777_Experimental_and_nume...

On cavitation in rubberlike materials

Microscopic voids can irreversibly grow into the macroscopic ones under hydrostatic tension. To explain this phenomenon it was suggested in the literature to use the asymptotic value of the hydrostatic tension in the plateau yield-like region on the stress-stretch curve obtained for the neo-Hookean model. Such an explanation has two limitations: (a) it relies on analysis of only one material model and (b) the hyperelasticity theory is used for the explanation of the failure phenomenon.

Molecular dynamics study of phonon transport in graphyne nanotubes

We determine the thermal conductivities of a, b, and g graphyne nanotubes (GNTs) as well as of carbon
nanotubes (CNTs) using molecular dynamics simulations and the Green-Kubo relationship over the
temperature range 50e400 K. We find that GNTs demonstrate considerably lower thermal conductivity
than CNTs with the same diameter and length. Among a (alpha), b (beta), and g (gama)-GNTs, g-GNT has the highest thermal
conductivity at all temperatures. By comparing the phonon transport properties of GNTs with CNTs, we

Theoretical studies on lattice-oriented growth of single-walled carbon nanotubes on sapphire

In this work, a theoretical study is performed to quantitatively understand the van der Waals interactions between single-walled carbon nanotubes (SWNTs) and sapphire substrates. The energetically preferred alignment directions of SWNTs on A-, R- and M-planes and the random alignment on the C-plane predicted by this study are all in good agreement with experiments. It is also shown that smaller SWNTs have better alignment than larger SWNTs due to their stronger interaction with sapphire substrate.

Stress-Life Fatigue Testing Basics

ADMET CEO and Chief Engineer Richard Gedney's article on fatigue testing applications was published on the Quality Magazine August 2017 issue. 

The article starts with brief descriptions of the four stages of metal fatigue:

Stage 1: Crack Initiation

Stage 2: : Slip Band or Stage 1 Crack Growth

Stage 3: Stage II Crack Growth

Stage 4: Ductile Failure 

Abaqus Python : reading odb file for field frame data

Hi,

I am running a python script to do some post processing on Abaqus odb file. While running it on Abaqus/Explicite output file I found it was taking more than usual time. And after timing the run I got the surprise that the most time consuming thing what just to read the time value for each frame. I have the script below.

A Hybrid Multi-Scale Model of Crystal Plasticity for Handling Stress Concentrations

Microstructural effects become important at regions of stress concentrators such as notches,
cracks and contact surfaces. A multiscale model is presented that efficiently captures microstructural
details at such critical regions. The approach is based on a multiresolution mesh that includes an
explicit microstructure representation at critical regions where stresses are localized. At regions farther
away from the stress concentration, a reduced order model that statistically captures the effect of the

Sandwich plates using Higher order theories

Hi,

While modeling laminated composites we use their material properties (stiffness matrix) to compute the ABD matrix. When E_z of the core is much higher than E_x and E_y, how can we model such a plate using 2D FEM?

Understanding the strength of bioinspired soft composites

Remarkable mechanical properties of biocomposites (bone, teeth, shell, antler etc.) are usually attributed to their special design where staggered mineral platelets are embedded in a protein matrix. Because of the high aspect ratio of the platelet the soft protein deforms in the shear mode predominantly providing the linkage for the hard inclusions. Mimicking Nature one might design materials with a similar architecture.
