Flexure

  1. A condition in which a thin section of a horn (usually the wall of a contour or relief, or the blade of a bar horn) has significant amplitude transverse to the stud axis.
  2. Any condition in which the transducer's loss is high, as indicated by a high temperature of the transducer's front driver and/or an intense noise is emitted due to some imbalance in the stack.
  3. A vibration mode in which a member vibrates transverse to its longest dimension (e.g., transverse to its length or radius). Flexure members can include rods, beams, plates, and disks. Also called "bending mode".
