(a) The 8 kHz component of the inclination as a function of x2 /a at t = −8, 0, 8, 16, 24, 32, 40 and 48 µs. Broken lines show the amplitude of the inclination of a flexural standing wave calculated by the classical elasticity theory for thin plates. (b) Waveform of the displacement (solid line) derived from the calculation of the inclination (broken line) of the flexural standing wave at t = 0. |
