too

Thank you very much for your comment! I am glad to hear it is helping you out! -DrDalyO

It is! Glad your enjoying the videos!

+Emre Yavuz thanks for watching! I will add it to my list of videos. Thanks

+Benito Berlanga thanks!

Yes! On the newer versions of Ansys you could!

Your welcomee!!

@@drdalyo sir can you post a video or link of video for finding the failure load for the beam by using ansys.its urgent (for my project)

Welcome!

You're welcome!

+Steven Lee np!

Please email me about this!

You could split the face geometry at the bottom to make a line, and then apply a displacement boundary condition making the vertical and lateral condition 0, and only allow for horizontal (FREE). This depends how you set up your axes.

Hi it should work without issues

You could do that, it would be a simpler way of solving the same problem. This way just shows you more detail.

@@drdalyo thanks Dr.

+Sarfaraz Ahmed you should be getting conclusive results, maybe your not setting your fixed support correctly?

Are you doing it in spaceclaim or design modeler?

You can change it from Vector to Components and enter the direction manually based on coordinates

read the comment of Drdalyo same procedure

+Pavan Agarwal you can create Construction Geometry, where you can then create lines and planes, from there you can scope results based on lines or planes. If you want just a node or element, using the newer versions of ansys you can click to show mesh, and use node or element selection tools to select the node or element, then create a named selection, and then in results use the named selection as the scope. Hope this helps!

You could also apply an offset force if you like. I did a split face because it was more visual.

+Piyush Aras What is the error message?

You can use node selection tool, and select the node, right click and create named selection. Then apply the force to that named selection.

thanks!

thank you!

+akram shaikh good question, cylinder would not be as easy. 1) simplify the problem and use a line body with a cylinder cross section and use similar boundary condition as this video. For how to do this, check my new linear buckling tutorial. 2) add two thin flat square plates at the ends of your cylindrical beam, then apply similar constraints. This should not affect the results near the center of the beam. 3) you can use Remote Displacement constraints on the cylinder edge, say left BC, constrain in Y, X, Z and the right BC only in Y, Z. Not sure of the results but you can play around with using the cylinder edge or adding BC to specific elements or nodes near your support. You might get singularities but you can just ignore them if your focus is near the center. Hope this helps! Thanks for watching. Drdalyo

Sir, I'm facing the same problem with cylinder beam. But, I dont really get your explanation. Can you please help me by recording it?

+Galloper What do you mean the collapse load? you mean ultimate tensile strength? that would just be when the stress in the FEA reaches the limit of the material your using. So for example basic steel has a yield at 250MPa and ultimate at 500MPa, so load the model until your stress reaches this value, but if its a simple problem you could just calculate it by hand would be faster. Missing some details here, please give me more information. Thanks for watching!

DrDalyo, thank you very much for your reply, collapse load is the load at which the beam fails. in other words, below this load the still safe,at and may be after this load the beam gonna collapse. I did the analytical solution and I just wanted to verify my results. Looking forward to hearing from you

+Galloper So then it is as i stated before, depending on your materials ultimate limit, it will fail at that point. so if your UTS is 500MPa, and the stress in ANSYS reaches that value, the material will completely fail.

+DrDalyO that was a good point to start with, also I wanna add the following. A structure may completely fail even well before yielding is reached. For some, buckling stresses may well below the yield stress. Thus the users have to calculate the "failing point", which takes into account the all possible failure modes, and compare the stress from ANSYS with that value.

@DrDaylo, I would like to ask that do you have any video in which you have simulated failure of a material when the load reaches the ultimate limit of that particular material?

+Justin Prendeville good question. No not really. Instead of applying a load, you can apply a "displacement" and then check the reaction forces to get an idea. Or you can do the trial and error but by using "parameters" so it will do it automatically

yeah good question!!! I too have some doubts can you tell how to do using trial and error?

+Liam Owens yes you could sketch a line and create a line body with an applied cross section, it would give very similar results and use less computing resources. See my video on linear buckling, i believe i use a line body. Also my video on a bridge i believe. Let me know if you have any other questions

First generation i5 by intel with 16GB ram.

+Piyabut Tangjitmanngamkul Your much better off using Beam elements, not shell. Draw a single line in modeler and then create a line out of it, then apply a crossection to that line (in modeler). So in this case it will be a square section, then apply the thickness/dimensions.

+abd eel Ansys R15, or version 15

+Mazin Omer your welcome, please see my other videos on my channel, I have one on RC Beam under impact.

yeah, thanks but i need static structural

+Mazin Omer I will post one in static structural soon.

+DrDalyO yeah i have problem in modeling reinforcement in beam and how to make it work with model as reinforced beam

+DrDalyO Since there are many people interested in learning how to create the model (geometry) as well, it'd be very appreciated if you could please show step by step in these first videos to get us familiar with ANSYS. Later videos, maybe we can focus more about other things
