Description

Recently, theoretical treatment is summarized as a generalized theory of AE [1]. It is clarified that crack kinetics and kinematics are recovered from a quantitative waveform analysis of AE. The crack kinematics are represented by crack type and crack orientation, which are modeled by the moment tensor representation. To perform the moment tensor inversion of AE, a computer code named SiGMA (simplified Green’s function for moment tensor analysis) is developed to process hundreds of AE records promptly [2]. Theoretical basis of the procedure is briefly discussed and practical application to civil structures in Japan is given.
