Description

Theoretical study of elastic waves excited by fracture sources has great importance in the field of acoustic emission (AE) [1]. Numerous solutions have been proposed to calculate the excited elastic waves in infinite plates for various AE sources [2–4] using complicated transformation and inverse transformation integrals. Although those solutions have found use in calibrating acoustic emission sensors [5], they are difficult to extend for studying AE waveforms in finite plates where arbitrary source and receiver positions and edge reflections must be considered. The finite plate problem is especially important in AE testing on small laboratory plate coupons, such as the standard tensile and bending specimens.
