Monitoring materials for strains and cracks

Creators

Description

A method of monitoring a material for strains and cracks is described comprising 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. The stress detecting member may comprise a metallic tube containing compacted ceramic powder, such as Al2O3 or SiO2. (author)
