摘要：

A piezoelectric sensor for the measurement of stress intensity factors (SIFs) of two dimensional cracks induced in a structure is developed. Two small pieces of piezoelectric elements are adhered near the crack tip so that the piezoelectric elements are placed close to each other and the crack tip's position is between them. The electric currents from the piezoelectric elements are integrated by integration circuits and the output voltages which are proportional to the electric charge induced in the piezoelectric elements are measured. The SIFs of Mode I (K-I) as well as of Mode II (K-II) based on the piezoelectric constitutive law and fracture mechanics are calculated. (C) 2002 Elsevier Science Ltd. All rights reserved.
