Abstract

This paper focuses on the interaction of SH elastic waves in a plate with a tapered free end. 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 and angles of free end inclination. 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. 

ABSTRAK: Kertas kerja ini adalah khusus berkenaan interaksi gelombang anjal SH di dalam plat yang mempunyai hujung bebas yang tirus. Plat ini dimodelkan sebagai satu struktur elastik separa tak terhingga, yang diandaikan mempunyai permukaan nirgeseran. Keputusan analisis berdasarkan mod pemadanan dibentangkan untuk pelbagai kombinasi frekuensi ternormal dan sudut kecondongan hujung bebas. Pemerhatian yang dibentangkan memberi panduan penting dalam menginterpretasi data eksperimental penggunaan gelombang berkutub mendatar sebagai satu kaedah penilaian tanpa musnah plat anjal.
