I am a PhD student on Timber structure.I have modelled timber beam using solid 45 element as 4 points bending but my result is overestimated.I have reviewed the literature and I have found that assigning Tsai_Wu failure mode in timber can solve the problem.I have found Tsai-Wu in following category in Ansys 12.1:Material model/nonlinear/inelastic/non metal plasticity/failure criteria/criteria3But Ansys appears the following error:*** ERROR ***                         

Hi 

 I am working on a project where fracture parameters are to be studied at the interface of a bimaterial body ..I would like your help for the following 

1 .If there is any Material or papers contentrating on the above plz let me know

2 . Which FEA Program gives or works best on this kind of prioblems 

thanks in advance 

Dear all,

I am doing MD simulation of  pullout of CNT+polymer.

It is mentioned in some lectures that before pulling process the CNT should be
relaxed using potential like Brener and during pullout, CNT is considered as
rigid.

If the CNT is completely free to move during relaxation
it will be deformed and distorted and will stop the simulation.

For solving this problem I think that CNT should free to move only in axial
direction during CNT relaxation. Anybody have idea?

i looking for a Fsi modeling in abaqus . anybody can help me?

thanks a lot

I am kind of new in computational simulation except for CFD. I have a cylinder which has a flange around it and a lid on top. Lid and the flange are connected by bolts and sealed with an o ring. Is it possible to simulate the load distribution around the flange due to tightening the bolts? Which package is most suitable for this comsol or Abaqus? I want to do simple simulation just to check whether the odd number of bolts are able to distribute load uniformly around the flange.

Thanks in advance.

Dear all:

I am currently pursuing Master of Technology at Indian Institute of Technology,
Kanpur (India) in Mechanical Engineering department. In my masters thesis I am working on analytical and numerical (FE) analysis of dynamic buckling of thin walled circular cylindrical shells under fluctuating radial pressure. I am expecting to submit my thesis by the end of August, and after that I am planning for a PhD. I want to continue to work on the dynamic analysis of structure for my PhD thesis, and I am looking for a PhD position in some European or Canadian University.
