Hi Lee.Conti,
first you should decide if you need to define your stress-strain curve using engineering or true stress-strain curve. I doubt that you will see drop after yield point in the true stress-strain curve. If you are going to activate large-deflection (large rotation) effects or large...
Dear ANSYS users,
there are FREE ANSYS ACT Apps developed in company available for download.
Figures Manager - app for efficient change of graphical preferences of multiple result Figures located in the Mechanical Outline tree. Advanced export of Figures included.
Energy Plot - app for...
The technology for concrete modelling based on SOLID65 is pretty old and not performing very well. You should use newer approach which is based on combination of:
- Reinforcing Elements (REINF263, REINF264, REINF265)
- material model for concrete TB,CONCR,
- and appropriate solid elements, for...
Hi,
you have at least 2 options:
1/ the simplest is way would be an element, for example linear/non-linear spring is capable to introduce a force dependent on deformation.
2/ you can create an loop in APDL which do following:
[ol i]
calculate first load step
*do...
Hi,
you can automate the task using ACT (ANSYS customization tookit) for Mechanical.
There basically 2 ways:
1/ create python script and use it in ACT console
2/ create ACT extension with GUI (toolbars, custom object etc). It more time expensive but the result is user friendly
The answer is...
Hi,
I am not sure that your command will work, I have never seen syntax like this in APDL.
You do not have to use *do loop, look at *vget command, you can use it like
*VGET, ParR, NODE, n,TEMP
where ParR is ARRAY (defined via *DIM command) and n entity nuber (usualy n=1)
The advantage is...
Bonias,
I am not sure which model is right for teflon, but if you can neglect strain rate, your choice is OK.
Be sure that you are using nlgeom,on (includes large-deflection or large strain effects).
I would recommend to load with displacements.
ANSYS expect TRUE stress-strain data. As far I...
Hi Benjamin,
you are using SOLID5 element with keyopt(1) = 0 so you perform coupled field analysis and UX, UY, UZ, TEMP, VOLT, MAG are your DOFs. Do you want to perform such a coupled analysis? If you are interested in thermal analysis only, change keyopt(1) to 8, in your macro ET,1,SOLID5,8 or...
Basically there are 3 options how you can customize your report:
1/ via preferences in Report Options dialog (link)
2/ or you modify the current report generator (link) - modification of some xml files is necessary
3/ for advanced and user friendly customization you can also use ACT, an example...
Hi,
I do not know if there a specialized solution for mapping of FloMASTER or Flownex in to FEM domain. But for example in ANSYS you can map results (temperatures, pressures etc) from other programs using scripting/programming. In ACT (ANSYS Customization Toolkit) you can program such mapping (=...
Hi,
try to create named selection containing bodies (volumes) on your contact side, you can name it "contact_side".
Then in APDL Comamnd Block you can select the elements via cmsel commad.
Your code will look like this:
SET,LAST !select results from last loadstep
! added code...
@TeoAlfa fist I would recommend to follow advice from L_K - use nonlinear frictional contacts and nonlinear material model and check the amount of plasticity

@ TheaAlfa
No I did not want to say, that your fatigue analysis results are not correct, because the pin is outside the tensile strength limit.
You should not use the tensile strength limit as strict criterion. Keep in mind that in reality have the material plastic behavior and the stresses...
The explanation why you can obtain positive number of cycles with stress higher than tensile stress might be elastic–plastic correction method (Neuber’s rule). This method is a part of the strain-life approach in ANSYS fatigue tool. You can find more information here on slide 16 here or here...
You can use External Model or Finite Element Modeller component and link it to your analysis, as shown in attached figure.
