Hi everyone!!
How are you doing??
I have a beam with two connections (pivot and simple supports) subjected to a bending force F of unknown value. Knowing the elastic limit of the material (340 N/mm^2) and the safety factor s=3 My question is to know if there is a possibility, with solidworks, to calculate the force F necessary to bend the tube.
Thank you very much!!
Hello@Issaka
The answer is no!
Indeed, finite element simulation, regardless of the publisher, only works in the elastic field. But what you want to do requires you to work in the plastic area, which SolidWorks Simulation doesn't do.
However, there is specialized software (trèscherware) for stamping and bending that allows you to identify the mode of deformation, especially when it has to be done in several passes.
Kind regards
PS: be careful with the vocabulary because your image shows that you are absolutely not in the case of a beam.
Thank you very much for the attention you gave to my subject. Which software do you recommend?? Thank you
Kind regards!!
Hello Issaka
In the case of tube bending, it is not a simulation in the RDM sense as in Solidworks. But software that calculates the exact shape after taking into account all the tightening, spring back, etc and that gives the right flow rate (automatic flow which is more and more integrated into the bending machine).
These software programs are especially suitable for CNC bending where they send the execution file to the CNC. This software also takes into account whether the forming is done cold or hot, in particular by thermal induction. The forces required for bending are made by parameterization according to the primary characteristics of the machine. A bit like in sheet metal work where there is a moderate concern about machine power in detail since the supplier gives charts of use according to the thickness and a range of steel, etc...
Kind regards.
PS: here is a software that does not answer your request but that illustrates my point
Hello Zozo_mp
This software is really very good, I had never seen this as well as the machine...

Here's an example

may the force be with you.
Hi @OBI WAN
For me, it's two but especially the first one that I love.

In the second we see the powers absorbed which vary constantly.
Just imagining the control software makes my hair grow in my head. Still, there are people who have it between their ears.
Kind regards
Hello @tous and @ @Issaka
I have come to correct, or rather complete, my first answer.
@Issaka asked for the possibilities, with solidworks, to calculate the force F needed to bend the tube.
In fact, and having taken the example of bending machines, I digressed a little from the subject because a bending machine makes a constant effort and much less than if it was done by folding with a Vé and against Vé having the required shape.
In the case of a bending machine (which no one is supposed to do ;-) ) on for example a 90° bending the bending force is relative to the entire material which must be deformed in a single force (all the molecules to be moved), while in the case of a bending machine the force is only made on 0.5° at a time and is almost constant.
Obviously, for the bending machine, it is the sum of the forces for each bent degree that is taken into account: but if we compare the total energy on the bending machine to the same total energy consumed on the bending machine, we can see that the bending machine consumes much less, especially in the middle of the cycle. The curve is almost flat with the bending machine and on the other hand with a very sharp Gaussian curve (small standard deviation) for the bending machine.
Wow!
Kind regards
Honestly guys!! You helped me enormously on this one. Thank you again. Sorry for the delay

THANK YOU
Hello @A.R and everyone,
Great to see Numalliance mentioned here, and thanks for sharing the video about our 3D bender - ROBOMAC 310! It's really cool to see our machines in action.
If you are interested in how our machines can be controlled and optimized, take a look at our Industry 4.0 section on our website. Here is the link: Industry4.0. You will find information about the software that comes with our machines, like the one you saw in the video. These tools can really help understand and manage the bending process, even for those of us who aren't engineering experts.
It's always great to see our machines mentioned in technical discussions. If you have any questions or want to know more about what our software can do for you, please visit our website or contact us directly.
Happy bending to all and may the force be with you!
Kind regards
Hello XLouis,
Thanks for this information, I'll take more time to take a look... @+.
