Transition from Solid to Liquid Superficial Waves in a Plate.

抄録

Even if POISSON's ratio reaches 0.5, neither M₁⁽¹⁾ nor M₁⁽²⁾ can coincide with the first order of superficial liquid waves. Each branch of dispersive RAYLEIGH waves should correspond respectively to sin αH=0 or sin βH=0. The former is not other than the dispersion-curves of liquid waves. On the contrary, amplitudes must be zero on the latter. Not always does the first order of dispersive RAYLEIGH waves correspond to the first order of sin αH=0.
