Simply supported beam under moving sprung mass is extensively used to model the bridge vehicle interaction.
It is also proved that the road profile has effect on damage detection.
How to model road profile in the ABAQUS for simply supported beam subjected to the moving sprung mass? Specially when a 2D simply supported beam is used.
Dear Hadi
if you mean how to model boundary condition, due to reflecting waves to the model and disrupting the responses, i believe you need to model infinite element where needed or add some absorbent boundaries which can absorb the waves and reduces its effect on the model.

Dear Saeed.
Thanks for your time and answer. A road is not smooth and therefore, the wheels of the vehicle get effected by this road profile in the real life. however, I don't know how to model this road profile in the ABAQUS. So far, I used bridge with smoothed road profile and manually add different level of noise to the recorded signals to consider different un-modelled effects.
