Hi all
I developed a Fnnite element code in Maple for Euler Bernoulli Beam Theory. Then I solved a cantilever beam with a vertical load at the free end. On comparing results with comercially available software, my results are good.
Finally I developd the FE formulation for Timoshenko beam theory. for the same cantilever problem, I introduced a small magnitue of shear modulus but the results are highly different from the Euler-Bernoulli beam.
Can any body explain this?
I got that there exist a property called ENTROPY;for which the difference in it's values at two states is (Q/T).but I can't get it's physical significance
I know that it represents the irreversibility of the process.But it doesn't sutisfy me.So if anyone can...
Hi all,
I am currently working on mooney-rivlin materials. I wonder if someone have tried to compute GI, GII and GIII with the EDI because I don't understand how to compute WIII with mooney-rivlin.
Thanks a lot

Hi,
I´m trying to simulate the contact between two gears. Each gear has 60 triangular tooth and all of them are in contact at the same time.
I have one external gear and one internal gear. The internal gear is driven by a torque applied at it center.
I know that I should fix the center of the gear but I don´t know how to do it with Abaqus. Ive started to use two weeks ago.`I´ve already done the tutorials and reading the Manual!.
Please Help me!!
Best wishes
My name is Aurelio Tronci and I am a PhD student at the University of Cagliari (Italy). My research topics are related to friction stir welding (FSW). The work done so far has focused on the application of the DOE technique in order to investigate the influence of welding parameters on the microstructural and mechanical properties of aluminum alloys (AA 2198 T3-T8) joints. At the moment I am interested in the development of a thermo-mechanical model of FSW with CFD, but I find it really difficult to find material constants (Sellars and Tegart law) for all the alloys I have to test.
Hello,
I have to do a simulation with two loads, a constant static load and a dynamic load that rapidly decreases. What is the best way to handle this? Should I create two steps one for the static load and one for the dynamic load and let the static load propagate, or should I just have one step where the static loas acts instantly and the dynamic follows an aplitude?
The problem with the two step idea is that when I create the static load as static, I cannot get the choice of Dynamic/Explicit on the creation of the next step.
Any ideas
I am new to abaqus. I am trying to simulate a simple model in abaqus- an elastic spherical shell being sucked into a rigid tube. the diameter to the shelll is thrice that of the tube and I want to study the large deformation of the shell into the tube.
hi everybody ,
i m quite new wd the ansys ,and was trying to simulate a problem of moving heat sourse (laser )
laser is having a gaussian beam distribution and has to move wd some velocity over a face of the plate .how could i model heat distribution of the laser and how coulad i move it wd some velocity..
i hope i m clear,plz help me out.
