Dear Colleague,
I have uploaded a video which shows the simulation of Slow-Fast crack propagation in ferroelectric single crystals:

Best regards,
I am an engineering doctor of School of Physics in Shandong University, China, graduated in July of 2011. And I have, during the doctor's research period, actively engaged myself in the area of thermoelectric material for 5 years, focusing particularly on the oxide thermoelectric material and module. I keenly desire to obtain a post-doc. Research position in a thermoelectric research group, and further continue the study of thermoelectric.Most of my work has published in peer-viewed journals. So I can do academic writing by myself.
Hello Everybody
I'm currently working on on the tubular weld of joint modeling using ANSYS
Problems that I faced was how to combine elements of the shell (for chord and brace) with solid elements (for weld) so that stress transfer can occur between two elements
one technique that I know is using MPC
is there any among you who has a tutorial about it ..?
please help.....
Dear Researchers, Scholars,
We are very glad to inform you about publishing a new quarterly journal, in Multidisciplinary Sciences and Fundamental Physical Sciences as,
“International Journal of Fundamental Physical Sciences (IJFPS)”
A new journal published by the Institution of Civil Engineers (UK) is available: Géotechnique Letters.
Average time to first peer review decision: 32.5 consecutive days.
First papers are available for free at the ICE Virtual Library: http://www.icevirtuallibrary.com/content/serial/geolett/fasttrack
Have a look!
Dear All.
May I please ask what is the relationship between Elastic modulus and hardness. Is it a direct relationship? i.e. higher the hardness, higher the elastic modulus.
Also, how could we interpret this relationship in materials like living bones?
Many thanks

This paper presents a stability analysis for fractal cracks. First, the Westergaard stress functions are proposed for semi-infinite and finite smooth cracks embedded in the stress fields associated with the corresponding self-affine fractal cracks. These new stress functions satisfy all the required boundary conditions and according to Wnuk and Yavari's embedded crack model they are used to derive the stress and displacement fields generated around a fractal crack.
