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
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.

this is often done in bridge loading by trains or cars
