    Mechanical test: influence of displacement measurement method on the load-displacement curve

    I asked the same thing on the Ansys student's forum: https://forum.ansys.com/discussion/19597/experimental-force-displacement-curve-different-measurement-methods#latest Tell me what you think of it. - Rodrigo

    Mechanical test: influence of displacement measurement method on the load-displacement curve

    Hi engineers, I don't know if this is the best forum to post this question, but here it goes. Regarding about a compression test on a sample with an hydraulic press: what's the real difference between using 4 LVDTs to measure displacement (like the one of the photo below) compared to using only...

    Weird deformed shape after plasticity in compression of plate

    Hi apwang, thank you very much for your response and explanation. A friend of mine also explained something similar to me about this topic. The thing is that I got surprised for having this deforme shape as I'm replicating another author's simulation (that also used plasticity but another type...

    Weird deformed shape after plasticity in compression of plate

    Hi everyone, I'm simulating an experiment regarding compression of an orthotropic plate. The deformed shape looks right if I do a linear elastic analisis, but after applying plasticity (von mises), the deformation around the loaded area disappears. I'm attaching some images. I'm applying CP...

    SHELL181 element size vs. thickness

    Hi guys, I'm working with plates subjeted to concentrated pressure perpendicular to plane forces, using thick shell finite elements, in other words, mindlin-reissner SHELL181 elements. The plate is simply supported on all 4 sides, its 2.450 x 2.450 mm2 by 70 mm thickness. The concentrated...

    SHELL181 X and Y displacements

    Hi guys, I'm studying a Cross-laminated timer plate under out-of-plane bending. I'm trying to obtain the X and Y (u and v) displacements through the thickness of the plate, stated by the ------- line in this picture: The NODAL SOLUTION plot of U,X and U,Y give reasonable results: Im...

    APDL code for solving multiple geometry cases

    Hi guys, I want to simulate several plates with same material, load and BCs but with different slenderness ratios, in order to evaluate stresses, like in the image below. In order to save time, I want to write the right APDL code to let Ansys calculate all these cases and get the results by the...

    Problem exporting ARRAY values to txt file

    Thanks sk_cheah, but I'm not using Matlab or Octave, I want to use the data in Excel. Vitkacy1989: Thanks for you help. I'll try that, but isn't there an easier way to export or be able to copy the array results from a list and the paste them into Excel?

    Problem exporting ARRAY values to txt file

    Hi guys, I'm having some problem with exporting an ARRAY with with 15 values in 1 column to a .txt file in order to copy it to excel. I tried googling but still don't understand the format required, and the warning saying that I can't use the command *VWRITE directly in the GUI. Any help would...

    Bi-sinusoidal pressure on plate

    Got it! A friend helped me. This is the APDL command to apply bi-sinusoidal pressure on a square plate. ! Definição da tabela a partir da função. *DEL,_FNCNAME *DEL,_FNCMTID *DEL,_FNCCSYS *SET,_FNCNAME,'bisin' *SET,_FNCCSYS,0 ! /INPUT,bisinusoidal_1.func,,,1...

    Bi-sinusoidal pressure on plate

    Thank you, but I'm actually using MAPDL. This is the plotted function in Wolfram Alpha.

    Bi-sinusoidal pressure on plate

    Good afternoon to everybody, I'm needing some help on applying a bi-sinusoidal static structural load on a square plate, like in the image. I tryied to find something useful on the web but I only got Transient analysis type of help. Could you give me some tips on the macro/apdl code for this...
