I'm going to run analysis for node assembly and I have bending moment i two directions. How can I apply bending moment in simulation window?
I'm going to run analysis for node assembly...
I'm not sure what you mean by this; what do you mean by a, "node assembly?"
A moment load can be added using a Torque load. You'll need to define an axis for referencing the moment about (if there isn't a cylindrical face that already exists).
apicture of what you're trying to analyze would be helpful here
same goes for a drawing of what the load will look like
see shaun's answer
What about the direction of the moment. Is it according to right hand rule?
Yes, right hand rule. You'll also see arrows representing the moment load in the simulation window for the load; if they're going the wrong way then check the "Reverse direction" box.
there will be an arrow showing you what direction you're choosing
Can you explain how to apply Mx? What I have to choose in the first and second box? Do you have a video?
That should work, but keep in mind that location of the axis/edge that you use defines the location the moment is about. If you moment is with respect to the neutral axis of the beam, then you need to define an axis at that location.
Can you please tell me what I have to do to define a moment about x-axis acting at the center of the web. What I have to choose in:
1. The first box with green face.
2. The second box with green gace and green edge.
have you defined an axis that goes through your point of interest?
as shaun mentioned, that is the initial key component to doing what you want to do
once you do that choose that as the reference and then choose the face you want it applied to and then the magnitude
I can't tell you exactly where to place your axis as I don't know all of the information associated with the problem; what I can do is provide you with an example.
Suppose I had an I-beam that I want to define a bending moment about the x-axis that is at the beam's neutral axis. In this case, the neutral axis is at the center of the beam, so to define the bending moment will require me to define an axis at the center of the beam.
First I define an axis at the correct location for my loading case (at the center of the beam) that is also in the correct direction for my loading case (along the x-axis).
I can now create a torque load on the face of the I-beam that is about the axis that I just created.
Thanks a lot
