Hi all, I am new to Comsol. I try to simulate the behaviors of a pre-stessed clamped-clamped buckled beam under transverse load applied on the middle point of the beam. Eventually, I want to obtain the force-displacement curve of the buckled beam. However, I don't know how to introduce the buckling. Also, I am unable to obtain the reaction force since I plan to apply the prescribed displacement to actuate the bistable beam from one stable position to the other one. Help me! I really need detailed instruction.
Thanks a lot!
