distributed load on framed beams

[Roxanne]

I am a student of mechanical ing and I wanted to ask you experts to help a project that we are doing in the faculty.
In fact...it is a doubt that came to me while modeling a simple square section bar (20x20) with length of 100 mm.
the aansys that I am using is the w12: basically, I block one of the two square faces with a fixed bond, and then I hit the load. and here, I fell into doubt.
if they select the rectangular face (fig.1) and pitch the load of 10 n (is an example)....ansys will see the load as distributed?? and in case it was a distributed load, how can I tell him that it is, for example, a triangular distribution? ? ?
Forgive me if, perhaps, I may have asked a question. I hope you want to help me

hello for distributed loads are surface loads (pressures) on the face of the element.
we apply them as follows:
define loads - apply - structural - pressure -on beams (this on beam3) type elements.

then you have to indicate the values of pressure to the nodes i (initial) and j final then entering different values will have triangular movements of pressure.
for other elements I think the procedure is similar.
I hope I've helped you.
Hi.

Good morning.
I wondered if with ansys (wb and also apdl) it is possible to simulate a load distribution along a circle arc and how to possibly do.

thanks to all those who will answer me

in workbench you can simulate the distributed loads in a tabular manner. As soon as I have time I can give you an example.

Thank you very much

Thank you very much

volaff hi, I noticed that your ansys version is very old so an example could not open it, I'll see to put on a mini tutorial plus a pdf explaining how to do it. Bye! :

Bye.
Actually we're using 16.2 but I didn't update the version.
I'll do it in the evening.

would you also have some notes on the contacts?
soon we will have to model threaded and welded connections and I find myself a little in trouble, also because I always used the iapdl and I will find myself to use the wb.

tincgrazio for disponibility

 

[lucadileta]

perfect then I give you the example with the 16.2. I should have something about contacts, however, ask if you have any problems. regarding the workbench has some limit but you gain in efficiency and, however, everything (or almost) what you use in mapdl you can return it via script even in workbench.

I used the apdl for the wb I am almost zero.

Thank you very much.

hi volaff, I gave you an example on the fly, in the .rar file you also find something about contacts and assignment of loads. If you have any doubt, ask.View attachment Ansys Wb.rarin the example I assigned a linear pattern of pressure. Take into account that by default the coordinate system for defining the load performance is the global one but you can obviously define new ones.

We thank you very much.
I just started using the wb, I can't do anything.
slowly I have to begin to know the commands.

Thank you for your availability.
