Proper ANSYS Element?

MJCfromCT

I am attempting to model a simple 2D surface in ANSYS that is subjected to a load in the 3rd dimension. My surface is a table top, in the X-Y plane. I have modeled it in 2D, and will give it a "simulated thickness". However, I am not sure which element type I can use to apply a force on the top of this surface in the Z-direction. Any thoughts? Thanks in advance.

For your application, you need to use a shell element.

Shell93 could be a good choice, it has quadratic interpolation with midside nodes and allows for large deflection. For the lower-order version of this element, you could look at Shell43 elements or possibly Shell63.

Thank you for the reply. It has been a while since I have used ANSYS, and Shell elements must have slipped my mind. :)

Which element type do you use to apply static force and dc voltage at the same time
for 2D or 3D model?

Mech_Engineer

I don't think there are any coupled Structural/Circuit elements. I suspect you will instead have to solve the problem as a coupled multiphysics problem, where the problem's multiple regimes are linked with imported initial conditions.

I can not think of any way to even apply that kind of initial condition. Perhaps there is some other add on to ANSYS that I am unaware of. I would think something like COMSOL would be needed.

There isn't anything COMSOL is capable of that ANSYS Multiphysics isn't; both are multiple physical domain FEA programs that have optimized solvers for iterating results from one solution regime into another. However it seems to me that a structural/electical coupling wouldn't wouldn't have any useful results.

I'm curious if the O.P. is really looking for something like a resistive heating effect that is coupled into a structural thermal expansion solution. This would a triply-integrated FEA problem solving for current density (electromagnetic solution), followed by a resultant temperature distribution from resistive heating (heat transfer solution), and finally a thermal expansion solution based on the temperature distribution (structural).

I am trying to simulate the interaction of two rectangular rigid blocks floating closely in a medium having relatively low elastic constant under simple shear condition. The space between two blocks was taken to be very low elastic constant. In the final result, I found the two blocks have overlapped to each other after a high finite strain value which is not true in practical. The blocks are supposed to keep distance among them. Can anybody suggest me how to avoid the overlapping?

I am using Ansys 10. I would like to draw an ellipse. How would I draw the keypoints from an external .txt file where the co-ordinates are saved in two columns?

I'm doing a project in analysis of friction welding of aluminium alloy. i need to know what type of element to be used in Ansys to get proper results.. pls anyone help..

I am doing my m.tech project on fracture mechanics..

I have to model orthotropic plate containing holes frm which 2cracks are emanating radially frm each hole.

my problem is i have to apply out of plane loading like bending moment and torsion.

So can any pls suggest for following problems

1.which element is suitable for above problem..?
2.how to model multiple cracks in ANSYS..?
3.How to apply moments over a plate..?

If u give suggestiong it will be great helpful to me..

thanks in advance...

I only use ansys to simulate magnetic project. but i never heard this method in ansys.

Is there a question in there?
