Modeling Defect Detection in Deep-Seated Tendons of Prestressed Concrete using Magnetic Flux Leakage

Prestressed tendons are a critical component in construction, contributing to enhanced load-bearing capacity and reduced cracking in concrete structures. However, due to material-related factors, individual strands may corrode and fracture (defects). Magnetic flux leakage (MFL) has proven to be an effective method for defect detection in non destructive testing. A significant challenge lies in detecting defects at depths greater than 20 cm, where detection accuracy is primarily influenced by the design of the MFL sensor.
