structural damping in a sentence

1. This close relationship between frictional and elastic stresses is called the structural damping law or, sometimes, the constant phase model.
2. This close relationship between frictional and elastic stresses is called the structural damping law ( 1, 2, 3, 4 ) or, sometimes, the constant phase model ( 5 ).
3. The structural damping law implies that frictional losses are coupled tightly to elastic stresses rather than to viscous stresses, but the precise molecular mechanical origin of this phenomenon remains unknown ( 1, 2 ).
4. In systems conforming to the structural damping law, the hysteresivity " h " is constant with or insensitive to changes in oscillatory frequency, and the loss modulus G ( = h G ) becomes a constant fraction of the elastic modulus.
5. III . The movement of the dynamic system perpendicular to the desired direction of the motion is usually the wasted kinetic energy in the system ( e . g . the vertical motion of an automobile suspension is wasted to heat energy in the shock absorbers, or vibration of an aircraft wing is converted into heat energy through structural damping ).
6. It's difficult to find structural damping in a sentence.
