hi ,

i am working with concrete beam in ansys, i what to konw how to now its failure manner??? ....how to know whether it is shear or flexural or crushing failure??.....and what is the difference between reaching 0.003 for the strain in concrete and not reaching it ???......what is the difference between getting a message said that we have a rigid body motion ......and a message said we have unconvergence solution???.......i have been struggling to find out the answer but i did get no thing yet ....

thanks

My company urgently needs to identify an individual or organization who can
fabricate a couple of hundred small Dielectric Elastomer transducers for an
R&D project.  The work could be done under contract.  We have
started making our own but it is becoming clear there is a learning curve plus
much trial and error and we are short on time.

If you think you might be able to make them or if you can suggest

Hello Everyone,

Im relatively new to Abaqus and I have to carry out a bifurcation analysis of a pipe. Once that is done I need to add the imperfection wavelength and amplitude calculated to the pipe and carry out further simulations.

Ive been trying very hard to get a direction as to where to start with it. Can anyone please help me with it? I know that you need to carry out a buckle analysis that will give you a wrinkle pattern on the pipe. This inturn will add up to the bifurcation scheme that you get.

Please, give a look to my research activity at http://www.ing.unitn.it/~bigoni and to my group at http://ssmg.unitn.it



If you are strongly motivated to work with a very active group in Solid Mechanics, we have a PhD position (3 years) available from January 2014, but the deadline for application is September 15, 2013!



The position is on a EU grant and is addressed to numerical/theoretical modelling of ceramics.

HELLO.

I WANT TO KNW THE UNIVS OFFERING MASTERS IN INDUSTRIAL ENGG IN US

PLZ DO LIST THE UNIVS 

I tried to perform a cohesive zone analyse in ANSYS, followed the turorial in HELP file. I used contact element to model cohesive zone. and I find out that:

1, if I use standard material of ansys to define bulk element, like defined by 'MP,EX,1,2.1e5   MP,PRXY,1,0.33 ' or 'tb,biso', I can get a reasonable contact result;

2, if I use usermat file to define bulk element, 'tb,user', then the solusion also is done, but the resulte seems not correct. two part of model not contact each other but  some sections of them are coincide.
