Abstract

1527287 Acoustic monitoring UNITED KINGDOM ATOMIC ENERGY AUTHORITY 29 April 1977 [14 May 1976] 20121/76 Heading G1G A method of monitoring a material for strains and cracks comprises attaching a stress detecting member to the material in such manner, that elongation of the material imparts a tensile strain on the detecting member, transforming acoustic energy emissions from the member into electrical signals and displaying the signals on an oscilloscope. As applied to monitoring a pressure vessel, a metal sheathed mineral insulated cable is attached to the vessel surface so that tensile strain imparted thereby to the cable produces sounds picked up by acoustic transducers, one attached at each end of the cable. Alternatively, the stress detecting member comprises a metallic tube containing compacted ceramic powder. The pressure vessel may have a grid of sheathed mineral insulated cables attached thereto.
