Earthquake in West China and lessons for us!
In Singapore, I have seen students who lost their relatives in last earthquake. I am very sorry about this, but I think there should be lessons for us in such disasters. Is'nt any cheap and easy way to reinforce building in the face of earthquakes? I hope such disasters make researchers concentrate on such important topics.

am a student of M. Tech. 2nd year. My project topic for dissertation is "Numerical & Experimental Estimation of Fracture Toughness of Some Materials using Compact Tension Specimen". In this dissertation I also wanted to develop a code which directly gives me the values of stress intensity factor just like ansys.
Actually I have develop an matlab programm (using linear quadrilateral element) which gives me the value of displacement at the cracktip using that i would be finding the displacement extrapolation method i would be calculating stress intensity factors
Creep and Material Property Correlations
Hey all, I'm looking for a method of determining creep properties of polymer products that is faster than applying a stress to them for an extended period of time. Is anyone aware of any relations between more quickly/easily attainable material properties and creep properties? Or is there any way to simulate an extended life test in a shorter amount of time?
Thanks for you help,

How to use mohr-coulomb criterion to simulate the indentation of BMGs in ABAQUS?
I encounter a big challenge now.
I wanna use mohr-coulomb criterion to simulate the indentation of BMGs in ABAQUS.However, there are many parameters confusing me.
We know the mohr-coulomb can be written as:
τc=k0-ασn
Wikipedia style publication in a categorized manner!
First excuse me for my poor English. Wikipedia-Style Open publish (suggested by Mike Ciavarella) can be a logical solution for many of Current publication and evaluation system problems, currently we utilize popularity for “quality warranty” and “Ranking” of papers and authors. Such factor can be a measure for evaluating the papers and authors in the new style too. The reliability of papers can even increase by this way more, Categorization of scientific papers is one of necessities of today’s scientific network.

Dear all,
I went through the forums and came across one similar topic, posted by alex_612 "Using Matlab to optimize the ABAQUS/Explicit FE mode", but with no replies. So I would like to bring this similar topic up again.
The problem:
1. I would like to open ABAQUS CAE thought MATLAB (which i have managed to do with the dos('command')), and then run a script as well, through MATLAB. I am using MATLAB 7 and would preferably like to run the whole process thought MATLAB.
How to measure the deformation in the soil
Recentl, in my research ,I need measure the deformation in the soil caused by the simulation of tunnelling construction in the labotory.In China, I have not found the proper devices to get the deformation occured under the simulation soil surface.Anyone who knows the devices or give me the advice will be appreciated!
