My 1st Paper!
Salam and Hi!
My 1st paper was published in Jurnal Mekanikal UTM in June 2008. Please comment and critic on my research works! The paper is here, PREDICTION OF PROGRESSIVE FAILURE IN WOVEN GLASS/EPOXY COMPOSITE LAMINATED PANELS.
Thanks!
How to obtain the exact true stress true strain curve from tensile test
Hi,
The data obtained from tensile test is not reliable after the point of maximum load as neck initiates and triaxial state of stress develops.There is lot of literature in this regard, Can anyone suggest a good method to obtain the exact load disp curve after necking.

A new paper on the nanoscale plasticity in twinned gold nanowires
A new paper titled "Enabling Ultrahigh Plastic Flow and Work Hardening in Twinned Gold Nanowires " from Dr. Sansoz's group just came out on the latest issue of NanoLetters. Attached below is the abstract and the full paper can be found at: http://pubs.acs.org/doi/abs/10.1021/nl803553b. We welcome any comment about this paper as well as our research.
Phase Field Modelling of Fracture Mechanics
Forums
Hello To one and All,
I am currently working on my Master's thesis in Computational
Mechanics and as the Title suggests, I am working on using phase field
theories to model fracture mechanics. The whole idea /concept of phase
field modelling in itself has been a very complex topic for me, as it
originates in superconductivity theories of which I have but a
superficial understanding. I am ok with fracture mechanics terminology
as I have worked on it before.
Question about stochastic Finite Elements
Hi to the community !
I would like to ask if anyone have some experience with stochastic finite elements in an industrial context ?
Would you know some software (free or commercial) package for stochastic finite elements ?
Why do I have the feeling that sfem methods which look to be very promising aren't used much in practice ? Am I wrong when I say that ?
Thank you very much for any help about that !

Chaboche elasto-viscoplastic model with plastic strain memorization and time-recovery in ANSYS
Hi, I am a reserach fellow of mechanical engineering in Italy. I need to implement the elasto-viscoplastic model of Chaboche in a user subroutine in ANSYS accounting also for the plastic strain memorization and for the static and dynamic recovery. In a next step I sould also need to incorporate the damage variable of this model.

Determination of material Mechanical Properties in ANSYS using Force-Displacement graph obtianed experimentally

Hi all.
I am a doctor course student in Biomechanics in Nagoya University - Japan.
I read a bunch of papers in which the determining the conffecients of hyperelasticty of the skin soft tissue was done by using FE Simulation of an expermiment that can be performed on the skin then TWEAKING (IN FACT ANSYS SUPPOSE TO HAVE AN ITERATIVE MODEULE TO DO THIS) the conffecients so THAT the force-displacement results from the simulation are close enough to the ones obtained from experiment.
NOW:
I have the Experiment results
comments on second page
I just noticed a new problem with imechanica: when a blog entry has received too many comments, additional comments will be placed on a second page but not linked properly. For example, the comment, "Work-free isochoric deformation", has a link node/5014#comment-10406 , which leads to the original blog entry rather than the comment. One can find the comment either by scrolling all the way down to the bottom of the page and then clicking "Next" or by a direct link, node/5014?page=1.
