Summary:
I am thinking of informally conducting a specific case-study concerning the FEA solvers. The reference problem is a very simple but typical problem from stress analysis, leading of course to the linear systems: Ax = b and Ax = Lx.
I seek advice as to what software libraries currently available in the public domain would be best to use---the ones that would be fastest in terms of execution time for the reference problem.
Dear all,
I have read the paper titled Haversian cortical bone model with many radial microcraks: An elastic analytic solution. My problems and the paper are attached.I hope you can see the problems and the corresponding paper. Thanks for your help.
Sincerely yours,

Dear community,
I need to implement the Chaboche elasto-visco-plastic model (with damage and without damage) into an Abaqus subroutine (VMAT or UMAT). However, I don't have any experience and the model is not so easy. Can anyone help me in some way?
Thank you very much.

hi all.
some time ago. i was measured the strees intesity factor (SIF) means electronic speckle pattern interferometry. i remeber used two equationes (in polar system) to compute by laest square method the KI and KII factors from measured displacement in the x and y directions.
my question is: do you find some utility or advanage develop a interferometer with radial sensibility?, i appraise your opinion or any suggestion
thanks

Hi, i am adarsh, graduate student in geotechinical engg
I am new to abaqus.
I have to use UMAT written in fortran for my projec.
I need to know or anybody having documentation about what is inutfile, UMAT, SDVINI (Related to geoechnical engg ) e.t.c so that i can learn regarding the same.

A postdoctoral fellowship is available in the Duke Computational Mechanics Laboratory, beginning in September of 2010 (with flexibility on timing). Funding for the fellowship concerns research in the simulation of dynamic fracture of polycarbonate. The ideal candidate will have experience in some combination of the following areas (in no particular order of importance):
Where to get information on the Mechanics of Bilayer Beam bending for Bridge & Cantilever beam?
Hi all!
I'm using Matlab and mupad in my research .I have managed to plot a few curves using mupad, a powerful symbol computation soft. Since it is theory solution, I want to add the experimental curves to compare the goodness.But i don't how to make the two softwares work cooperated.
Any suggestions will be appreciate.

Dear everyone,
Recently I have read the paper--Haversian cortical bone model with many radial microcraks: An elastic analytic solution. In this paper, I can't understand the dislocations Burgers vectors (bt and bn), the following words and the corresponding expressions(6a) and (6b). The paper is attached.
Now, if it is assumed that bt and bn are continually distributed
over the microcracks, the shear and normal stresses could be
formulated as (6a) and (6b).
Waiting for your help. Thanks.
