Hi all,
I am working with an orphan mesh of a finger made up of:
1) elastic epidermis layer
2) viscoelastic dermis layer
3) hyperelastic fats layer
4) bone
NLGEOM is turned on.
Tie constraints are used between the layers and the bone
I wish to make this finger 'touch' a cubic object however the job always fails as it is not able to converge.
Will anyone be able to advise on this matter?
All,
I am writing to introduce DNAD, a Fortran module I wrote for automatic differentiation of analysis codes written in Fortran including those legacy codes written in Fortran 77. Although only implementation using Fortran 90/95 was carried out, it is straightward to translate it to a language you like such as c/c++.
Original research papers, for oral or poster presentation, are invited for the following areas:
Hi;
I am looking for a way to model a reinforced beam by ANSYS.
Is it possible to model the bars and the concrete part seperately and then glue them together.
What is the routine way to do this?
Is there any tutorial available?
Thanks;
Media
Hi, I finished my PhD and I am looking for a summer school or a language school in English. And also I want to improve my Meshfree knowledge and programming knowledge. My education is funded by government ( or my university). How can I find a school or university? And what is the procedure for acceptance?
Dear all,
Can anybody give me some papers on the grain size T3 2024?
I know it should be 10-100 μm or so. But I want to get a more precise data and cite it in my journal paper.
All suggestion or papers are welcome. Thanks.
Dear all,
Sry for posting this topic again. However, i've meet problems when simulating powder compaction. The following parameters is what i have i used
Elastic : Young modulus 40
Poisson Ratio 0.35
Plasitc : Drucker Prager angle of friction 33
here is a simple question
I have modeled the reduced section of a tensile test specimen in 3D (a simple cylinder; falt surface in x-y plane, length in z direction). I applied a load on one flat surface of the cylinder, and put the opposite flat surface as a symmetry plane.
When I plot the result after the simulation of a tensile test, the cylinder moved in the direction perpendicular to the application of the load. I was expecting it only to increase in length in the z direction.
I used for the first time the CINT command with ansys, and I get strange results:
negative values
very different values for 2 adjacent nodes on the crack front
non converging values (values fluctuating from 1 contour to another, going up and down)
Also, i don't know what are the units of the J integral (I am using SI units, dimensions in mm ). It's important to know so I can calculate the SIF
How can I know what contour gives the best result? what are the units of the Jintegral in the SI.
Anybody have some information for me?
I was going through these papers:
1.P.K. Sarkar and S.K. Maiti, 'Prediction of mode-1 fracture toughness of unidirectional fibre composites with arbitrary crack fibre orientation from its lowest or matrix fracture toughness'. int. J. Fracture, vol. 40. pp. R91-R96, (1989).
2.S.K. Maiti and P.K. Sarkar, 'A method of calculation of total strain energy release rate and its layer-wise distribution for an arbitrary through the thickness crack extension in a composite laminate', Engg. Fracture Mechanics, vol. 36, pp. 639-646,(1990).
