2-D Point-to-Point Contact Elements (CONTAC12) Input Listing: vm236.dat Test Case
A beam of length L = 80 µm at a height T = 0.5 µm is suspended 0.7 µm above a ground plane and is clamped
at either end. Using this beam, model the hysteresis (pull-in and release behaviors) when it is placed under
electrostatic load. Figure 236.1 Beam Under Electrostatic Load
