How is it possible to simulate the force required to bend this
steel bar under the terms of the attached drawing.
You must enter the information of the steel to exceed the elastic limit.
Simulate 3.0 is it able to do
Thank you for this video.
But the bar does not slide, it remains fixed in the wall.
It's just the part B - C which must bend turn to point B.
And the question is how much force should be applied to achieve this result?
Maybe you can have a try by following these steps:
First,you should know the vertical distance between point C and point C' when the bar bends down;
Then set a forced displacement(prescribed translation) which equals that distance;
The third,make a force measure of the forced displacement,hope these can help you!
Thanks for this example.
You mean the plasticization of beams in soul full in flexion.
Simulate can't go this far in the calculations.
Hello 学 蒋
Thank you for your response.
The blockages on the axis you do on "points"?
You have used the method of optimized design studies?
Thank you for your shipment.
Yes, blocking means forced.
I'm on W7 32-bit pro, I do not yet use Creo 4.0, so that I
buy a PC 64 bit with W10 pro.
Yes, Denis, it is possible to analyze this, but you will have to use solid elements with material plasticity, and also large deformation analysis + contact analysis. If you want to model the plastic collapse, you cannot model the load using a "load", instead, you will need to model the load using an enforced displacement.
The nonlinear solver is sensitive to mesh, I advise to use brick/wedge elements to model the beam.
Here are a few pictures from a plastic collapse analysis I did a few years ago. I recall that I also had an animation, but I can't seem to find it. Unfortunately I can't run Creo where I sit now, so I can't re-create these results.
In this case I have no contacts, but the load is axial, and what you see here is post-critical behavior, if you enforce a vertical displecement, along the edge of the beam end.
Thank you for your response and your explanations.
I put the demonstration in GIF, because the link is no longer valid.
