Acoustic emission and vibration analysis application equipment is needed to detect the ultrasonic wave induced by laser pulses. As a laser pulse is deposited on the material surface, it excites broad-band and multi-modes ultrasound. As the induced ultrasound propagates in the material and reaches the surface, it creates a surface distortion. In order to measure the waveform, a laser interferometer is used to quantify this surface distortion.

The National Structural Integrity Research Centre (NSIRC) is a new industrially-led, joint initiative between TWI and lead academic partner Brunel University, alongside the University of Manchester, the University of Cambridge and a number of leading industrial partners.

The initiative is funded by industry and by grants from the Regional Growth Fund (RGF) and Higher Education Funding Council for England (HEFCE). Funding for equipment for NSIRC is being provided by HEFCE and is available in the period up to 31.3.2015 to assist in establishing a new facility at the TWI site in Abington, Cambridge and to purchase equipment to be used in the centre.

The equipment will be purchased by Brunel University but the procurement process is being undertaken by TWI on Brunel University's behalf.
