Abstract :
A finite-element analysis is presented for reflection of the fundamental symmetric Lamb wave at the free edge of a semi-infinite elastic plate. It is shown that the edge resonance phenomenon is very sensitive to the value of Poisson´s ratio. For a smaller value of Poisson´s ratio, this phenomenon occurs at a lower frequency and the solutions vary more rapidly with frequency.
