The maximum shear stress field for an experiment with α = 25° and P = 7 MPa ( Fig. 2A ) shows that the speed of the rupture tip is very close to c R and follows closely behind the circular shear wave front that is emitted at the time of rupture …
WebMar 4, 2024 · For example, in , in the context of sagittal propagation, it is claimed that ‘as the frequency increases, all modes converge to the Rayleigh wave propagation speed’. Figure 14. Frequency spectrum for symmetric antiplane Rayleigh–Lamb waves (solid, black) superposed onto the LWLF approximation (dashed, red) (η = 0.1, H = 10). WebJun 24, 2024 · The effect of linear frequency on the Rayleigh wave speed is observed as being more significant near smaller values of \(e_2\). Figure 3 illustrates the speed variations of the Rayleigh wave against the diffusion nonlocal parameter \(e_2\) for different values of elastic nonlocal parameter \(e_1\) when f is fixed as 1.6 Hz.
