Why always warning Comment field is required
I want to reply to other people's comment , but when I finish the reply and clikc the "post comment" it always warns comment field is required , I Do not know what is wrong. If someone knows the problem, please tell me, thank you very much!!!
Java for High-Performance Computational Engg. / Sciences?
In the past few days at iMechanica, there have been quite a few messages dealing with different aspects of programming, libraries and so on...
It would perhaps be timely, therefore, to ask:
Do you have any opinion about using Java in numerical analysis (NA) / FEM / CFD etc.---i.e., in computational engineering and sciences (CES)?
Do you have any experience or hard data concerning performance of Java vis-a-vis C++ or FORTRAN, esp. for large systems, or for high-performance applications? Any pointers?
Please leave a note... Thanks in advance...
modelling of cohesive zone in Ansys
Dear Friends,
I try to make simple model of crack propagation in Ansys but cannot get the clue what i dont include in programming file that I cannot see the propagation of crack, the cohesive layer doesnt break, simply stretching like rubber. Could somebody to give me advice on this topic?
thank you!

Near-incompressible analysis
Hello all,
I am studying some simple finite elements for 2d near-incompressible analysis. Particularly, I am interested in the MINI element. It is basically a 3-node triangle element with nodal pressure and displacement degree of freedoms enriched by a bubble function. Could someone that has some experience with these elements point me out about advantages and drawbacks of using these type of elements?
Thanks,
Alejandro.
Self-consistent Modeling of plastic and viscoplastic polycrystalline materials
I am a freshman of researching the macro response of metals with micromechanics scheme. Now,I have to build a self-consistent modeling of plastic and viscoplastic for polycrystalline materials. However, it seems difficult for me as I have little knowledge of polycrystalline and its mechanics propertities.
If you know some systematic books or papers about my research area. please let me know. Your kindness will be great appreciated!!!
What yield criterion must I use?
Nowadays I am analyzing a study of a hip prosthesis including the bone. I am making the FEA/FEM analysis by Pro/Mechanica software. Metallics materials are titanium alloy (Ti-6Al-4V) and Chromium-cobalt-molybdenum alloy (CoCr29Mo). So they are ductile materials. I understand the main load is the flexural load on the hip.
Compressive strength/failure test on brick
Hi everyone. I'm new to this forum and quite new with FEA.
Currently i'm trying to find compressive strength or maximum failure stress on a modeled brick. Is't possible? What parameters or properties do i need in hand in order to proceed?
Regards,
KenLo
