Sh wave scattering at a broken tapered end of an elastic plate

Research output: Contribution to journal › Article › peer-review

Abstract

The paper focuses on the interaction of SH elastic waves in a plate with a tapered free end. The tapered free end is also considered after imposing a truncation to represent a broken tip. The plate is modeled as a semi-infinite elastic structure, which was assumed to have traction-free surfaces. The results of the analysis based on mode matching are presented for various combinations of normalized frequencies, angles of free end inclination, and sizes of broken tip part. The reported observations form important guidelines for the interpretation of experimental data when using horizontally polarized wave as a mean for nondestructive evaluation of elastic plates.
