Investigations of AE Signals Emitted From Dropped Indenter on Steel Pipes’ Surface

Acoustic emission (AE) are stress waves created by the material deformation, which could be utilized to detect impacts of objects within different mechanical systems. In a mechanical system, impacts from dropped masses are pertinent to realistic wave sources where is to improve precision of source l...
