Multistability and snap-through behaviour of a bistable clamped strip from Adaptive compliant structures for flow regulation

The application of a transverse load to a bistable clamped strip in its first stable configuration causes snap-through into the inverted stable shape. The applied load increases until it reaches a critical value. At this point the beam snaps through a region of instability, where applied load decreases, reaching a second stable branch. Upon load removal the structures settles on the secondary stable state.
