Bending moment of a simple beam

[hl3]

Hello everyone,

I'm new to Abaqus as well as the forum. I'm working on a project and I'm doing very well so far, being new to Abaqus and all, but I eventually got stuck.

It is a simple beam with a cross section, two loads and four support points. I split the beam into 3 parts so there are 3 sections to add BCs to. The first 2 sections are 4m in length and the last is 3m. There is a 25Nm moment force at the end of the 3m section and a uniformly distributed load of 1500 N/m in the middle section.

I've added all BCs and loads appropriately and the job completed with no errors. What I need from the model are the bending moments, but the option "SM1" is not there in the list when I go to select it. I understand that this option is only available when working with beams and I have triple checked that all the steps I've done prior to this has "beam" selected.

I don't know where to go from here. I would appreciate it if someone could guide me in the right direction.


Thank you

I think I got it figured out. Correct me if I approached it wrong though.

I went to the "Field Output requests" in the model tree and opened up the manager and toggled on SF, section forces and moments and resubmitted the job and SM is now there.

I'm assuming if it's there then it has to be correct.

Any feedback will be greatly appreciated.


Thanks

I wouldn't assume that it is correct. You should confirm with some hand calculations. Even if you need to simplify the problem a little to make the hand calcs workable it will at least give you an idea.
