problem with element table

[optimumcarbo]

hello to all

I have a problem with ansys v14 apdl. when I ask to perform the analysis of the equivalent stress of von mises on a thick tube, hinged on an extreme, inside the etable window I receive the message: s is an invalid label. the etable command is ignored.

as element type use pipe 288 and define the thickness and diameter of the pipe in sections. I calculate the bending arrow but it doesn't let me calculate the equivalent stress.

Can anyone help me?

Thank you.

practically compute me only the deformed without stress.. help

Now I don't know how the pipe288 element works.

I would say to use the help by writing in the command bar: help,288

in general to plot the deformation of the structure you must use the command: pldisp,0


ps: I think you wanted to calculate (view) the deformations, but I'm not sure, you don't understand!! !

Thank you very much for the answer. the deformed with relative arrow I managed to win it. my problem and that I can't plot anything about stress (such as von mises) and the beam colored all red

try to take a look at the plnsol command, typing in the help

help,plnsol

However typing in post process plnsol,s,1 you should see the first main voltage, analogously for second and third (plnsol,2 and plnsol,3)

to do. As usual I only get deformed and the bar gets red without stressing me. I think I'm wrong to choose 288 pipes or I get something in the options of this item.

I don't know the element, never used...

I think you have to activate the display with the true section of the beam and not the representation through its axis
You do it by activating
/eshape,1
followed by
plnsol,s,eqv

to return to display using axis
/eshape,0

Look at the help no? it was enough in search of ansys insert pipe288 and the answer was there ..
ansys previews a verification manual (they are nothing but file example on which the goodness of the code is verified. many also call them "patch test"
the example vm12 answers your question ... not to miss I also place the file

eih64 clear and concise as always!
You're great!
