| Summary: | Generally, solid materials will emit energy in the form of elastic waves when
internal defects occur in these materials. The releasing signal phenomena caused by
internal defect is called as acoustic emission phenomena. Internal defect usually happens
when the structure is under loading. Defects can play a role as signal sources. These
releasing signals indicate internal defects in materials.
This report discusses about research of acoustic emission phenomena as indicators
of internal defects in materials or structures. Experiment conducted in the laboratory
proves the existence of the acoustic emission phenomena scientifically. Laboratory data
proves the existence of acoustic emission phenomena when structure under study
experiences deformation or has tendency to defect. Verification of the acoustic emission
phenomena can be used further as a monitoring method for internal rock structure defect,
such as bridges, cantilever pole building, dam, tunnel, cave, underground nuclear waste,
and others. |
