Structural Health Monitoring (SHM) is the use of metrology techniques and sensors to provide a continuous assessment of the state of engineering structures.

For owners and operators of assets such as bridges, buildings, power plant, wind turbine, aircraft, chemical plant etc., the ability to accurately monitor material condition and structural performance via reliable, intelligent and remote operating structural health monitoring (SHM) systems, will result in significant benefits through a reduction in operating and maintenance costs and advanced warning of component failure.

NPL is currently involved in projects assessing many traditional and novel sensors for monitoring structures such as bridges and industrial machinery, and also the environments outside and within those structures. Because SHM can produce a large amount of data, we are at the same time investigating data mining and visualisation techniques that can help extract and present the salient information.

• Strain measurement and mapping
  • Strain gauge measurements (24 channel facility)
  • Fibre optics (Fibre Bragg Grating)
  • Digital image correlation
  • Electronic speckle pattern interferometry
  • Raman spectroscopy (incl nanoscale Raman Spectroscopy)
