Acoustic-Emission Monitoring Of Lap Joint Fatigue Cracks, Siddharth Kannan
Acoustic-Emission Monitoring Of Lap Joint Fatigue Cracks, Siddharth Kannan
Theses and Dissertations
Structural integrity is a pivotal consideration in the field of engineering applications, and understanding the behavior of materials and joints under various loading conditions is critical. This thesis presents a novel approach to detect and analyze fatigue induced cracks in various test specimens using Piezoelectric Wafer Active Sensors. This approach is widely used in Structural Health Monitoring applications involving acoustic emissions that can be captured using PWAS which in turn gives the surface response to applied stresses. The ultimate goal of the research is to identify the length of a fatigue crack originating from lap joints and to develop a …
