Acoustic emission for structural health monitoring during load tests
Acoustic emission for structural monitoring during load testing: sensors detect sudden plastic deformation or cracking in the material to locate damage in real time.
Physical-Chemical Mechanism of Action
Acoustic emission arises from the propagation of elastic waves emitted during sudden plastic deformation or crack growth in the material. These waves can be detected and located by sensors.
Metallurgical Relevance & Welding Risks
Acoustic emission is an important tool for structural monitoring during load testing. It enables early detection of damage such as cracks or deformation, reducing the risk of collapse or failure.
Workshop Practice & Action Instructions
Use acoustic sensors to monitor load tests. Place sensors at critical points on the part and monitor constantly. If anomalies in emission frequency or amplitude occur, report immediately and analyze the part further.
