Rayleigh waves speed
WebRayleigh Waves. Rayleigh waves are the slowest of all the seismic wave types and in some ways the most complicated. Like Love waves they are dispersive so the particular speed at which they travel depends on the wave period and the near-surface geologic structure, and they also decrease in amplitude with depth. WebIts inverse c R = 1/p R x is the Rayleigh wave speed, which is slower than both P and S waves. The Rayleigh wave speed is c = 0.91β for an elastic half-space with λ = μ, and vary …

WebJan 1, 2024 · According to the continuum fracture theories, the crack velocity can reach the Rayleigh wave speed, C R, when a large enough energy flux flows to the crack tip (Freund, 1998). However, a terminal velocity, defined around 0.85C R, has been revealed for the (110)[1-10] cleavage under tension (Cramer et al., 2000). WebNov 28, 2024 · The secular equation of Rayleigh wave is derived in an incompressible nematic elastomer half-space with impedance boundary conditions. This secular equation provides a relation between the wave speed, frequency, rubber relaxation time, director rotation times, non-dimensional anisotropy parameter, chain anisotropy parameters, shear …
