Characterization of the damage process in GLARE®2 using an eddy current technique based on HTS-SQUID magnetometer

In this work an eddy current technique based on a HTS-SQUID (superconducting quantum interference device) is used to evaluate the relation between the magnetic field response and the damage process of one of the most promising fibre metallic laminates known as GLARE®. In particular the magnetic field response due to impact loading at energies ranging from 5 to 36 J has been detected. The magnetic field signal from GLARE® specimens in the presence of mechanical damaging is discussed according to a simple electromagnetic model.
