Moving Force
Hi friends I want to define a moving force with a special velocity in Abaqus, like a train force on a bridge.Is it available in Abaqus ? If yes how I could define it?Thanks

Hi Akumar!I read first article but I couldn’t access the second one. In the first article you said there are 3 trends to define vehicle loads: 1-moving force 2-moving mass 3-moving oscillator And you...

Time varying displacement can be defined only in a step. So once you've defined a dynamic step, go to Load Module in Abaqus. Then create boundary -> from drop down menu, select the step you would...

Hi, The surface for 3D beam can not be defined as the unique surface normal can not be determined from nodal connectivity. Therefore, 3D beam surfaces can only be used as slave surface in contact...

View ArticleThe Difference
The difference among all these three is quite simple. Moving oscillator is the most general approach, and moving mass and moving force are two extremes. In moving force we account for only the load...
