Explicit finite element perfectly matched layer for transient three‐dimensional elastic waves (2009, methodology): “The above description of the PML uses the linear elastic constitutive law (Equation (3b)) for the sake of notational and algebraic simplicity, but in general, the PML can use any linear (visco-)elastic material model [18, 35, 36].”
An unsplit convolutional perfectly matched layer improved at grazing incidence for the seismic wave equation (2007, methodology): “Regarding seismic wave propagation, the PML has been successfully applied to both acoustice.g., Liu and Tao, 1997; Qi and Geers, 1998; Abarbanel et al., 1999; Katsibas and Antonopoulos, 2002; Diaz and Joly, 2006; Bermudez et al., 2007 and elastic problems e.g., Chew and Liu, 1996; Hastings et al., 1”
The Newmark scheme as velocity–stress time-staggering: an efficient PML implementation for spectral element simulations of elastodynamics (2005, background): “In this case, the second order in the time scheme is preserved, avoiding loss of efficiency, intrinsically owing to second-order equations, which require additional variables in time stepping (Komatitsch & Tromp 2003; Basu & Chopra 2004).”
