A variation of Euler's contained column theory. The curve is formed by constricting the material laterally and clamping its ends to a lower platen. The bell curve is position between two platens for compression. A compressive force is then applied in the downward direction. As the bell curve is compressed it shifts to form a relatively low frequency sine wave. As the downward force increases, the system shifts to a progressively higher wave frequency with corresponding lower amplitude. This effect continues till the radius of the waves becomes prohibitively small and the yield strength of the material is passed. If the force is removed prior to passing the yield point of the material, the flexible spring material will return to its original shape. The force needed to shift the curve to the higher frequency waveform increases at an exponential rate, as opposed to the linear rate of most normal springs. The threshold force needed to convert the low frequency wave to the higher energy level wave is much greater than the maintenance force used to keep the waveform in its new stable state. Such a relatively light weight spring with an exponential stress / strain rate and energy absorbing / self dampening effect, through phase change, could have a number of useful mechanical applications.

This spring requires an exponential increasing force to convert the low frequency sine wave to the next higher frequency sine wave. It is more analogues to electromagnetic energy in their waves or electrons in various energy shells.

Most wave springs are pre-shaped into the alternating undulations. The spring material in this video would layout flat if it was taken out of the end clamps. In most wave springs the ends are free to slide out as the load is applied limiting the spring’s resistance to that which is required to bend the material along each point.

This is a good demonstration here on how this works.
