Applying loads where amplitude and POSITION change with respect to time

Applying loads where amplitude and POSITION change with respect to time

Applying loads where amplitude and POSITION change with respect to time

(OP)
Hi everyone

I have a load where both the amplitude and position change with respect to time. How do I create this load on ABAQUS, without using a subroutine. I know how to have time-varying amplitude of a load, but I do not know how to create time-varying position.

For example (this is not my specific model, but it's a similar idea), how would you model the stress on a road due to moving vehicles on ABAQUS.

If the only way to model problems like these are with a subroutine, how can I quickly link a FORTRAN compiler with ABAQUS?

Any info would be appreciated

Thanks!

RE: Applying loads where amplitude and POSITION change with respect to time

Oops, sorry. I did not read your post carefully. If you are going to need to vary the position of a load, I think you will have to use a subroutine. There is a LOT of information available online regarding linking Abaqus, Visual Studio, and Intel Fortran compiler.

Are you new to this forum? If so, please read these FAQ:

Got it. Thanks IceBreakerSour!

Does anyone know if there is a way to do this without going into subroutine/FORTRAN stuff?? I would rather not go thru the trouble of linking a FORTRAN compiler with ABAQUS (I have no Idea how). I would really like to do this without a subroutine, but I think IceBreakerSour is correct.

RE: Applying loads where amplitude and POSITION change with respect to time

you can define a point; load the point; make contact between point and surface; move the point

this is often done in bridge loading by trains or cars
