Thanks so much for the tutorial! Sadly what I was taught during lectures on FEA did not help much when it comes to modelling in practice. The world needs more quality videos such as these! Keep it up!
First time i have watched video in which guy explains non linear analysis with simplicity. I am trying to learn ansys from past year. This video taught me non linear analysis. I feel like how much ever i thank you its not enough.
The first video of ansys on youtube which explains each and every step conceptually, otherwise you would see videos of ansys on youtube where u would find a person doing steps and not explaining why they are doing that particular step .. keep up the good work.
Keep on doing what you re doing, these Tutorials are so compressed with informations and tricks and I like that. The examples could get more difficults :p its always a pleasure to watch you resolve them. I had always a problem workinig with 18.2 when importing a STEP File (originally from Solidworks) and try to apply a force or a certain surface (not the whole surface just a section of it), without going through the Construction Modeler since its an imported part. Thanks for everything !
thanks a lot for the time and effort you spent doing this video, actually I come from a cfd background and I found your step by step approach really valuable, please keep sharing these tutorial videos & highlighting the general workflow. very useful loved it, sub & liked
you've been saving lives!! please teach us how to do a tensile loading experiment!! P.S. i needed to reduce the mesh to 10 mm, due the student license version.
Defenetly best explanation and Tutorials on youtube about FEM ! By the way, what happens if you are using linear material ? Do you get the same stress and deformation ? So that means if you want to analyse a problem you have to know before that it will be non linear ?!
bro help here plss.... at last the node one during result its only showing the node not the whole little visible bean like you ...and the graph is also straight for node ...why????????//help pls
I tried to redo this in Ansys 2022 R1 and with Pressure it doesn't work. I did everything acc to the video. With Force I get it to knick. But with pressure no luck . Any idea why ? Thank you!
Hi, for Multilinear data you have tried to enter 0.1 as the first value in plastic strain. but asnsys won't accept it as the first point should be 0 plastic strain against yield stress.
How can I model an orthotropic plasticity material behaviour in the LS Dyna workbench? I used the APDL code for modelling of orthotopic bilinear material in static structural but apparently, I can't use the macro code in LS Dyna. Is there any method applicable to create this material model?
good morning. Please, does someone know what to do when this error occurs: "reference to an object not set to an object instance". It occurs when I try opening Ansys meshing, and I don't know what to do, I cannot understand why it happens now.... please, I am desperate!
It basically means how many sections you want to divide the force by when calculating. The higher number of substeps usually means your solution will converge better without any error. So lets say I want to divide my force by 5, that would be the initial number of substeps. If the computer finds that it can solve the solution using less during the run then you can allow it to be lowered to say 2, which would be your minimum. And maximum is if say the computer cant solve with 5 substeps and needs to increase it, you set the top limit to say 10. Note the higher the maximum the more time it may take to solve depending on your model
I am in CFD with experience in Thermal and Fluid Field... But now planning to expand it to Aero-thermo-Structural... Basically for FSI ( Fluid Structural Interaction)
Should we need to check the results (equivalent stress and equivalent total strain) with the input non linear curve to check whether the result is following the input curve given..ex:1st point stress 250Mpa, strain 0; 2nd point stress 260Mpa, strain 0.5.consider we are getting 255 Mpa from analysis, then strain should be in between 0 to 0.5 or it can be beyond 0.5?
At 4:30, shouldn´t the yield point be at a strain of 0.02? Also, it´s labelled "plastic strain", does it mean you have to subtract 0.02 from the total strain to get the plastic strain? I would have though the yield point would be at a plastic strain of 0.00.
At 4:30, the graph shows only the plastic region (I know its slightly confusing how ansys does this). So your not seeing the linear region. There is a straight line from 0,0 to 250,0.01. After which, is the non-linear region or plastic region. If its still not clear, let me know in comments here.
Hi, thanks for your kind reply! I checked the ANSYS Help and it mentions the first point corresponds to the yield stress and strains are entered as plastic strains. I understand the first point should be plastic strain=0.002, stress=yield stress, because this is how yield stress is most commonly defined (permanent plastic deformation of 0.2% after unloading). Also, past the yield point I assume the values are true strain and true stress as opposed to engineering stress/strain. I wish to input the stress-strain curve of a given material as published on the MIL-HDBK-5 and I'm afraid I'm not doing something right. The first issue is true vs. engineering. The second issue is plastic vs. total instantaneous strain. Unfortunately the ANSYS help focuses on the Mechanical APDL way of submitting the information rather than the Workbench user interface.
Hi, just found the answer to my question here: studentcommunity.ansys.com/thread/multilinear-kinematic-plasticity-material-model-create-from-a-stress-strain-graph/
@@drdalyo Hi, at 4:23, I am confused as to why your first strain input (0.01) remains yellow, as if it's not correct. This is also happening in my simulation and I'm not sure what the correct input is. Do you have any insight?
Guys, I have a basic question for you. My Ansys engineering data source is missing, I mean, when I try to choose a material on the libraray there are a few material on there. So , how can I find them or import them? What might be the problem? Please help me. Thanks in advance.
Unfortunately I was unable to get close results, I suppose it's something to do with the calibration of the software, I don't know how to calibrate it ...stuck :(
@@drdalyo Hi thanks, that's the first thing I checked, I now suspect it's to do with the mesh, whenever I change the mesh there's a cross on the solid geometry. The software is a free version.
it's a very helpful tutorial. I was wandering if you could help with doing a push over analysis for multi story rigid frame (more than one indeterminate). thanks,
Hi, I'm facing this problem on Ansys. Kindly help me to solve this: "your product license hasnumerical problem size limit, you have exceeded these problem size limitsand the solver cannot proceed "
Hi! If you're using Student license, try to make mesh less frequent. That problem occurs because your edition only has to work up to a certain threshold. (This of course makes calculations a lot less precise). Hope that helped, had the same problem with Patran Student Edition
Mike is right. You need to increase the element size due to limitations of your license. You can attempt to use mirroring in order to save element count. Meaning u can slice your geometry in half and insert a mirror normal to the slice plane. Any yes, its annoying that the results will vary because of larger element size..

in that case, you can make a named selection for the whole area and then chose it to put pressure or force on the named selection area.
Love your lecture! Clear, detailed!

Why does the analysis result show stresses beyond yield point when in theory only strains should increase and stress should remain at yield?
After adding bilinear isotropic material, my ANSYS does not respond. Even though I reinstalled it.
bro help here plss.... at last the node one during result its only showing the node not the whole little visible bean like you ...and the graph is also straight for node ...why????????//help pls
Kindly, have you used Ansys Mechanical 2024 R1?

Is it wrong to plot a chart of vonmises stress vs strain? Can you please explain multilinear isotropic model for a brittle material?
Hi, for Multilinear data you have tried to enter 0.1 as the first value in plastic strain. but asnsys won't accept it as the first point should be 0 plastic strain against yield stress.
many thanks for your effort can you please make video on adding frp layers for steel beam on ansys ??
Is it possible to turn the loading condition into a cycle and conduct a fatigue analysis this way?
Thanks in advance
Yes it is! You can probably find other videos on this (not by me).
Some portion of this 0.5 meter I-Beam was inside the wall that means >> in that portion it has got fixed support in its bottom surface
