When a solid undergoes a plastic deformation or fracture, part of the stored strain energy is released as elastic stress waves which can be sensed by sophisticated instrumentation. These stress waves are termed acoustic emissions even though the amplitudes and frequencies involved are usually outside the audible range. This study demonstrated that acoustic emission technology is becoming increasingly more suitable for field applications in civil engineering. Further research relating to reinforced concrete, soils, paving materials, and passive transducers is clearly justified.
