Minisymposium proposals for the 12th U.S. National Congress  (USNCCM12)

to be held July 22-25, 2013 in Raleigh, NC are solicited from people

interested in organizing sessions in their area of expertise or interest

and/or wishing to honor particular individual for their sustained

contributions or a special honorary birthday celebration.

The proposal should contain the minisymposium title, a one-page

description of the objectives of your minisymposium as well as the

The result of two workshops on ‘Space - the Final Frontier - What Potential for European Space Policy?’, this special issue of Space Policy gathers a range of papers, many by young researchers, which examines the contribution space policy can make to the European integration process.

Some materials exhibits a Brittle/Ductile rupture during a test (ex: traction test) one can notice that by examining the shape of the stress/strain curve, some people try to examine the rupture surface via a microscopic observations, the surface's reliefs can be helpfull to find out the main microscopic mechanisms responsible of the final rupture of the considered material, for those who have a significant experiance in this fiels, what are the most imprtant methods ( or steps to take) used to classify the rupture of a studied material to take into account as a sufficient arguments for this

hi dears

i have som problems in my project that should be simulated  with abaqus .

The

elements contained in element set ErrElemExcessDistortion-Step2 have distorted

excessively.

There

is only one excessively distorted element

The

ratio of deformation speed to wave speed exceeds 1.0000 in at least one

element. This usually indicates an error with the model definition. Additional

diagnostic information may be found in the message file.

Can anyone please tell how do we differentiate between "Crack propogation" and "Fracture initiation". A simple example will be much appreciated!

Hi Everyone.

Can anybody please expalin me what is the meaning of "PIECEWISE" in Ls-Dyna material "MAT_PIECEWISE_LINEAR_PLASTICITY(MAT_24)".

 Thanks in Advance.

hello dear friends,

I am trying to conduct a pushover analysis on a 2D dam model by abaqus.the material is concrete and is modeled by damage plasticity. the problem is because of the softening issue ,while I apply force, the solution would not converge with a low magnitude of load and it remains elastic so I can not obtain a complete pushover curve. I have very little time to get the results so I appreciate anyone who would help.

Thanks

Hi everyone,

I want to ask, does anyone know how to design vanes for unsymmetrical elbow? At least can you give me some calculation recommendations to design it? I am doing air simulation inside ductings for my final project. Thanks all
