software of interest to mechanicians
i have modelled a 3D RC beam and strengthened it with FRP and used cohesive elment for modelling the adhesive .
so for finding theinterfacial strain between concrete and FRP ,which strain must I opt for namely , E, NE, LE, PE
And i want to know what theses stand for(E11, NE11, LE22) . I hav read it in manual but can I get more information on this
Hi everyone,
I just started to use the Abaqus FE program and I would like to ask some help. I would like to determine the elastic properties of a composite material therefore I designed an representative element but I need to constraint the nodes of each surface to achieve uniform deformation at each nodes on the surface. I tried the multiple point constraints but I alvalys got an error message saying that:
Hello,
I want to know that is there a novel way of defining several two dimensional contact pairs in Abaqus/Explicit. I know that abaqus has the capability of defining a general contact but it is restricted only to Abaqus standard and 3D Abaqus explicit problems.
I have a 2D plane strain problem where I have to specify more than 1000 contact pairs in the assembly between similar instances of the same part. Is there a fortran subroutine that could be used to determine so many contact pairs?
Thanks,
Tuhin
Hi,
I am doing project in Journal Bearing. I want to run Contact Analysis in ABAQUS to understand the Tribological properties. Could you please help me to learn the Contact Analysis in ABAQUS.
Thanking you.

I came across a wonderful site a couple of weeks ago. nb.femhub.com
FEMhub is still at its beginning stage, but it can already do lots of interesting stuff. For someone like me who teaches numerical/computer methods in engineering at a developing country where computing is costly, tools like FEMhub are very much welcome.
More about FEMhub on my website. Try out the example worksheets and I think you'll be pleasantly surprised.
As we all know, finite element matrices are sparse and many memory can be saved if their sparsity is exploited. Due to the latter, we are often provoked to declare the nxn stiffness matrix as a sparse one just before the element loop. Be careful of this method since the larger the matrix the slower the assembly operations. There is a better and more efficient way to code the assembly procedure in Matlab. I will show how to accomplish this. For the sake of simplicity, the stiffness matrix of the two-dimensional heat conduction problem on the domain (0,1)x(0,1) is considered.
hello to every body ;)
Iam hasani- gradute student
I'm new user in adina. i worked by ansys and abaqus for several projects.
in adina when i choose control>solution process...>adaptive meshing> full the program return it to none!.
i tried to understand about the reason. but in fact i can not find the problem.
i think in program , there are some constraints that should be change before the full adaptive meshing.
please help to find the problem. thanks
Download your Free Abaqus SE at: http://campus.3ds.com/simulia/freese
SIMULIA Academic programs would like to offer you a complimentary copy of our Abaqus SE (student edition). Now students can have their own personal finite element analysis tool to use on or away from campus. Abaqus Student edition is ideal for students using Abaqus as part of their coursework as well as for practicing engineers who wish to become more proficient with Abaqus.
Dear Colleagues,
IOSO optimization technology has been used in turbomachinery for more than 20 years and applied on real-life objects like aircraft and power engines. Let me offer you some more examples.
First example:
Dear all,
I need a free autoCAD software to model the complex 3D geometry of human brain. It is desirable that this software should generate output files readable to Abaqus/CAE for mesh generation. I wonder whether these is such a software available. An alternative way is to handle the geometrical modeling myself but I need to know the details of the file format used by Abaqus/CAE. Does anyone have a clue?
Thank you very much!
