Definitions for "SHAPE FACTOR"
It is the ratio between two frequencies, the frequency at a specified attenuation on the roll-off curve to the corner frequency at its specified attenuation, usually -3dB.
The ratio of the area of an elastomer body subjected to a compressive load to the sum of the areas which are free to bulge. As the shape factor increases, the strain produced by given stress decreases. This is a critical consideration in avoiding heat build-up in dynamic applications. It is also important in static load bearing applications such as structural bearing pads where compressive stress relaxation versus time is to be avoided.
A ratio of two bandwidths. Typically, a comparison of the passband of a filter to its stopband. In bandpass filters, it is the stopband bandwidth divided by the passband bandwidth.
