Hi everyone:
The initial displacement D=1.05mm, is placed on the end of the cantilever beam, to solve the velocity response of the beam end. First, I select space dimension 2D, and add physics Beam, but the simulation result is wrong, when I select space dimension 2D, and add physics Solid Mechanics (solid) , the simulation result also is wrong, the velocity curve is increasing against time. Now I select space dimension 3D, and add physics Beam, but the simulation result is not the same to the experimental result and analytical result. I am confused. Hope some one give me a advice, thank you! Details see attachment.
