I'm looking for postdoc or engineering position in energy storage or power source area (development of supercapacitors, lithium-ion batteries, etc.), where I could apply my knowledge as well as many-years hands-on experience in electrochemistry, materials science and chemical engineering. d.gromadskyi [at] gmail.com

Dear friends,

           I am simulating sound propagation in mild steel.

frequency=5MHz mesh size=0.5mm

time incriment of wave amplitude=1e-9

instead of giving force at a node i have given boundry displacement

U1=5.8e-10

U2=-8e-10

instead of showing sound propagation, my entire specimen(mild steel with 15 mm thickness) deflecting like a wave.I would like to know 1)what is the reason for that deflection?

2)what may be the possible solution?

Hi,

I have a bar with an analytical rigid surface attached at the free end with a RP at the centre of it. I am applying a rotational BC of UR3 = 0.017 (1 deg) with respect to the Z axis, but the resulting rotation at the end of the bar is more than 1 degree. Any idea why? Or how to have a full control of the twist of the bar? Also the bar deforms in shape where the end at which the twist is applied expands, making this cross-section bigger (clearly no the deformation expect for torsion). Input file attached in a word doc. 

Hi all,

    I've been facing a very strange problem now when I'm using abaqus to finish RVE multiscaling simulation: so far, what I've done is successfully  linking fortran and abaqus to run the whole calculation. At first, I met a small problem--- overwrite the old files(y/n)?---which has been solved by adding a "abaqus_v6.env" file whose content is as follows in the abaqus working direction:

TECM is a premier interdisciplinary session for the presentation of new advances and research

results in the fields of Theoretical, Experimental, and Computational Mechanics, i.e.

computational fluid mechanics, computational solid mechanics, computational heat transfer,

experimental fluid dynamics, and combining them with real life industrial applications. The

session will bring together leading academic scientists, researchers and scholars in the domain

of interest from around the world.

This year's talks are now at https://registration.gputechconf.com/form/session-listing

A large number of interesting talks from the 2014 conference can be found at http://on-demand-gtc.gputechconf.com/gtcnew/on-demand-gtc.php

There is even one talk on structural mechanics in the 2014 conf.

Hi every one,

I'm doing the prediction of residual stresses using Deform-2D (orthogonal cutting) and I have a problem in axial component  I found its value is very large.

Have any one already did a work like this and if yes can anyone give me more details about the unloading phase: removing the tool from machined surface, cooling phase, boundary conditions applied during these steps etc..

Thanks
