HI,
I am performing a non linear buckling analysis in ansys using shell 181 element. My geometry is made up of composite material and has a shell structure. The shell is subjected to torsion at one end so as to buckle throughout it length. the other end is fully constraint.
My problem is how to apply this torsional moment at the free end.
anybody please help me.
Hi all,
When we do a non-linear buckling analysis, initially we introduce some imperfections (mode shapes of mode 1, 2 etc) from eigen buckling analysis. Then we multiply the load with eigenvalue of the first mode. This load is applied on the structure having imperfections. Now put on non-linear geometric option and run the analysis. At bifurcation point we get non-linear buckling load. Non-linear buckling load comes close to eigen buckling value.
Decription of my problem is as follows.
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;

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.
