Comparison of vibration measurements of elastic and mechanically lossy (visco-elastic) materials, using fibre grating sensors
Comparison of vibration measurements of elastic and mechanically lossy (visco-elastic) materials, using fibre grating sensors
The paper compares results when measuring oscillatory strain in elastic (Al alloy) and visco-elastic materials using in-fibre Bragg gratings. These show the effects of self-heating in the latter, when mechanical losses arise, and also show the effects of materials creeping at high strain levels. Results are also taken for highly-elastic metallic substrate materials when a visco-elastic damping medium is in close contact. The results show that care must be taken, not only when monitoring fast oscillatory perturbations in visco-elastic materials, but also when choosing fibre bonding cements or protective coatings for use with fibre gratings.

Abstract
The paper compares results when measuring oscillatory strain in elastic (Al alloy) and visco-elastic materials using in-fibre Bragg gratings. These show the effects of self-heating in the latter, when mechanical losses arise, and also show the effects of materials creeping at high strain levels. Results are also taken for highly-elastic metallic substrate materials when a visco-elastic damping medium is in close contact. The results show that care must be taken, not only when monitoring fast oscillatory perturbations in visco-elastic materials, but also when choosing fibre bonding cements or protective coatings for use with fibre gratings.
