Constrained layer
WebDec 7, 2014 · Non constrained damping is any layer of goo adhered to a rigid structure. Studies show that the approach damps resonance but that a significant amount will be … Constrained-layer damping is a mechanical engineering technique for suppression of vibration. Typically a viscoelastic or other damping material, is sandwiched between two sheets of stiff materials that lack sufficient damping by themselves. The ending result is, any vibration made on either side of the constraining materials (the two stiffer materials on the sides) are trapped and …
