About osmotic pressure
Recently, I studied Prof.Suo's lecture "Advanced Elasticity", node/725.
The following is explaination about osmosis pressure in the lecture.
Is imechanica evolving into mechanics.craigslits?
Lately I am feeling like imechanica is becoming a craigslist for mechanics than a forum. Most recent blogs are simply ads that do not generate any discussion. Neither do questions from people get any reply, not any where near to what it used to be.
The last journal club had about five or so replies and the current one has no comment with two days to end.
Is it just me or does any body else feel the same too? I feel we have to think about how we can have a community here than just a repository of mechanics related stuff.
Mathematical background for X-FEM
Hello,
Tsai-Wu criteria on ANSYS
Hello everyone.
I'm trying to apply the Tsai-Wu criteria to a composite plate in ANSYS. I'm using the SHELL99 element.
However, when I input the data for the criteria an error occours and ANSYS won't show me any results on the criteria.
Can someone help me? How do I use this criteria and what data should I use?
Thanks in advance

2nd spatial derivatives from isoparameteric elements
Based on my limited knowledge of FEM, I find it is difficult to use isoparametric elements for any problem whose governing
functional involve the second (or higher) partial derivatives of the unknown
functions. I hope some computational mechanicians can help me on this. Currently, I have a formulation derived from micropolar elasticity which has a functional involving second partial derivatives of the displacements. Thanks a lot for any of your suggestions.
Material model for high cycle fatigue
In fatigue analysis, it is common to use S-N curve from database for spesific material, and some time for spesific way of loading. Is there any way to predict fatigue from direct simulation? For example, giving cyclic loading (10^5 times) and the material will suffer damage and eventually failed. In some FEM codes (MARC, LSDYNA, etc) there is Lemaitre-Chaboche model used to analyze material behavior under low cycle cyclic loading.
Thanks in advance
