Dynamic behaviour?

Sat, 2017-11-04 06:58

In reply to Journal Club for March 2017: Architected Materials

Dynamic behaivour seems often overlooked when new materials are invented. Prof Qingming Li and I have published a long review paper on the dynamic compressive behaivour of cellular mateirals in International Journal of Impact Engineering, which may be of interest for those who work on foams, honeycombs, wood, architected lattices, metamaterials and so on.

How to define Drucker-Prager model for soil in Abaqus

Wed, 2017-11-01 22:50

In reply to interaction property

When the pipe moving on the seabed (sand), the soil will be form an configuration named "soil berm". 

Please see this link to get more information:

https://www.youtube.com/watch?v=VdQpjkwNKl4

The soil bearm is as a results in extreme large deformation. So i must use Eulerian domain to solve this problem.

Can you help me to define Drucker-Prager model for soil in Abaqus?

Thanks in advance!

Dear Zhansheng,  Thank you for bringing in the paper, would you introduce us some aspects of the growth kinetics of dendrites?  Thank you.  -Kejie

Great to know your active

In reply to Postdoctoral Position in Textile Simulation and Optimization

Great to know your active research in textile composites. You might be interested in our code TexGen4SC which can perform a ultra efficient yet accurate computational homogenization for textile composites using mechanics of structure genome

Kejie, great job!

In reply to Journal Club for November 2017: In-situ Mechanics Experiments on Battery Materials

good summary.

the following was a experimental results of dendrite.

RSC Adv., 2015, 5, 69514

Direct in situ observation and explanation of lithium dendrite of commercial graphite electrodes
Zhansheng Guo,Jianyu Zhu,Jiemin Fengb and Shiyu Du
Lithium-ion batteries (LIBs) have some serious safety problems, such as lithium dendrite formation during charging/discharging cycles that may cause internal short-circuiting, fires, and even explosions. A new double-scale in situ experimental setup, which can record all phenomena during the electrochemical testing, was developed. Lithium dendrite growth behavior of commercial LIBs during small-currentdensity charging at room temperature was observed in situ. The formation, growth, and dissolution of lithium dendrites, and dead lithium residue were all observed and recorded using this new experimental test system. A detailed model of lithium electrodeposition and dissolution processes was proposed. The electrode structures were determined by X-ray diffraction (XRD). The surface morphologies were examined by scanning electron microscopy (SEM). The texture and surface morphology of the graphite active layer affected lithium dendrite initiation as well as its growth processes

Look up the BAQUS example 2.1

subroutine for the cohesive zone method

Tue, 2017-10-31 23:10

In reply to good point

Dear Prof. Gao,

I am a new learner of CZM. I know that you are willing to share a subroutine about the cohesive zone element. I have searched your webpage, but I couldn't find it. Could you send it to me? My email address is E0256440@u.nus.edu.

Looking forward to your reply!

Many thanks for your help.

Please contace me if you are

Deviatoric and Skew Tensors

Sat, 2017-10-28 08:52

In reply to What's the difference between deviatoric tensor and skew tensor?

There two different additive decompositions of a tensor: Symmetric & Skew, and Spherical & Deviatoric. The Skew and Deviatoric tensors are both traceless (The first principal invariant is zero in each case). A Skew tensor is antisymmetric and has only zero elements along the diagonal when represented by the components provided by the Cartesian coordinate system. The diagonal components of a deviatoric tensor are not necessarily zero; but in order for the tensor to still be traceless, the sum of these add to zero. 

Symmetrical as well as shpherical tensors are also both symmetric in the sense of being indistinguishable from their transposes. In the case of spherical tensors, off diagonal elements (Cartesian Representation) all vanish. In regualr symmetric tensors that are not spherical, off diagonal elements do not necessarily vanish.
