Abstract
This paper presents solutions for guided wave motion (Lamb and shear horizontal) due to tensile and shear cracks in an isotropic plate using elastodynamic reciprocity. Finite-length through-thickness cracks are considered via Huygens' principle by representing them as a superposition of point cracks. Far-field solutions are then derived in order to simplify the results and facilitate a direct comparison of guided mode excitability due to various cracking modes. Relatively short- and long-length line cracking are compared to point cracking for the fundamental modes S-0, A(0), and SH0. It is shown that the A(0) modal response is the most sensitive to crack length, with S-0 and SH0 being relatively insensitive. Additionally, the radiation patterns of S-0, A(0), and SH0 are relatively insensitive to crack length. The results have applications in acoustic emission monitoring of plate-like structures, where modal responses may be used to characterize crack growth.
