Modelling concentrated loads

Hi there,

I am new to this forum and was suprised to find an Abaqus section. I will be the first to post. My problem is that I want to model a concentrated load moving linearly on a beam segment back and forth. Can someone help me in doing this?

Thanks

Hi,

there are a few possibilities to do this:

  1. Set up separate load amplitudes for the concentrated load at each point/node along the beam. This is only really useful for a couple of points.
  2. You could use a rigid beam/surface/body with contact set up between your beam and the rigid object. This might be more computationally intensive than what you are looking for.
  3. You can use the DLOAD user subroutine. Here is an example of something similar: defining moving pressure loads

I hope this helps, best regards,

David
