Thanks for the nice and simple tutorial!

Why should one select solid section for plane stress elements? The Thickness information is not in the geometry and it is not given in the section property as well. So is the thickness info not required for plane stress elements?

hi, how can I model a moving unsprung mass problem instead of a moving load model on a cantilever beam in Abaqus?

Hello; I would like to ask you about the "orientation subroutine" in UEL. I have an anisotropic cylindrical structure and I need to define a cylindrical local coordinate system, it's easy to do on Abaqus, but I couldn't do it with the UEL. thank you so much.

Prof.Jeffers, Thanks for your helpful video. 1.With that example beam, I wonder if I want to plot beam's deflection and stress contour in color like Abaqus CAE do, How can I do that?

@aejeffers 2 жыл бұрын

The only way to visualize the results from a UEL is to superimpose the UEL results on standard Abaqus elements

@aejeffers 2 жыл бұрын

You can extract any data that you want but you won't use the ODB file. Instead it will be the FIL or DAT files. You'll need to read the Abaqus documentation on how to do this.

Nice tutorial. I have a question. How can be defined the UEL in Abaqus, except the inp file? The UMAT, is defined by the ''Edit Material'' -> ''User Material''. Is there such a button for UEL?

@aejeffers 2 жыл бұрын

As far as I know, the input file is the only way to specify a user defined element

May I know how to apply residual stress in steel plates.

@aejeffers 3 жыл бұрын

Residual stresses are prescribed as an initial condition in Abaqus. If you have a uniform initial stress, this can be done in Abaqus/CAE. If the initial stresses are nonuniform, you have to use the SIGINI user subroutine. Not sure if I can get an example up on this any time soon, but you may be able to figure it out by reading the Abaqus documentation.

Hi how can I find the formulas behind the output results in abaqus?? To be specific I want to know formulas which the software uses to give the reaction forces..

@aejeffers 3 жыл бұрын

You would have to look at the documentation (specifically the Abaqus Analysis Users Manual) to find the actual solution procedure.

Hello, What an awesome tutorial. Thanks a lot. However, I have one question. Can you please explain how to link abaqus with the intel One API compilers??? Also, a separate question, is there a tutorial on how to write the subroutines in c++ and linking them into abaqus?? Thanks a lot.

@aejeffers 3 жыл бұрын

Since the oneAPI compiler technically is not supported, I don't plan to add a video to show how to do this. Regarding user subroutines, Abaqus only supports subroutines written in Fortran, at least that is my understanding.

Plane strain analysis is done by selecting plane strain elements instead of plane stress elements. I think the rest of the model set up is the same.

A pinned beam with point load at midspan has a deflection of PL^3/48EI. Set this equal to the desired imperfection and solve for P.
