Unfortunately, I don't know what COMSOL has in the way of follower forces, i.e. applied forces which remain in the same orientation with respect to the contact point on the member, but that's what would be necessary to maintain the tangential nature of a bending force. As the end moves under deformation, the force must maintain its angle against the end (or it drops to zero in the direction of interest once the bend hits 90 degrees). The second scenario - with one end fixed and one force on the other end - would be the best to produce the scenario in your diagram:I need to model kind of bending deformation of a solid rod to a semi-circle using COMSOL. Could you please help me with the loading types and constraints that I need to use for this model. Also, I need to consider my elastic-perfectly plastic with different yield stress at compression and tension. Is there any option for this in COMSOL?
I really appreciate your help.
OneWhiteEye, the misalignment of the corner that you show is about four stories into the collapse and occurs after the upper section shortens by about four stories. The reason there was no deceleration is that the first stories to disintegrate where 98, 99, 100, and 101. This is quite clear in the video. Why would stories above the initiation floor disintegrate before anything is contacted below in a natural collapse?
Less than 1% of threads are closed. They get closed when they go off topic or stray too far from the posting guidelines.An open question to Mick. What's the point of locking threads? Could you write down the reason. I'm relatively new here but it seems they are often closed.
