Snap-through of buckled beams or shallow arches may be utilized in some MEMS devices. Such behavior can be induced by applied moments at the ends. A simply-supported uniform shallow elastic arch is analyzed. For equal end moments, the critical value is compared for arches with a sinusoidal shape, a circular shape, and a shape that maximizes the critical moment. For unequal moments, the effect of the amount of loading asymmetry on the critical value is determined for sinusoidal arches.
