Abstract
Impact and fracture monitoring on CFRP structures are important issue to assure the structural reliability. We have developed an in-situ source location system using Acoustic Emission (AE) monitoring for CFRP anisotropic structures. AE in thin plates, such as CFRP structures, propagates as Lamb (plate) waves and the velocity of AE depends on frequency. Furthermore, in CFRP structures, velocity of AE has orientation dependence due to structural anisotropy. Therefore, the source location method for CFRP structure becomes complicated, and the source location required much time. In this study, we used affine transformation in the source location algorithm to reduce calculation cost. The calculation time for each source reduced to 15 msec within the reasonable accuracy.
