On the stability analysis of perfectly matched layer for the elastic wave equation in layered media
Kenneth Duru, Balaje Kalyanaraman, Siyang Wang
In this paper, we present the stability analysis of the perfectly matched layer (PML) in two-space dimensional layered elastic media. Using normal mode analysis we prove that all i…
Accurate simulations of nonlinear dynamic shear ruptures on pre-existing faults in 3D elastic solids with dual-pairing SBP methods
Kenneth Duru, Christopher Williams, Frederick Fung
In this paper we derive and analyse efficient and stable numerical methods for accurate numerical simulations of nonlinear dynamic shear ruptures on non-planar faults embedded in 3…
On energy-stable and high order finite element methods for the wave equation in heterogeneous media with perfectly matched layers
Gustav Ludvigsson, Kenneth Duru, Gunilla Kreiss
This paper presents a stable finite element approximation for the acoustic wave equation on second-order form, with perfectly matched layers (PML) at the boundaries. Energy estimat…
The perfectly matched layer (PML) for hyperbolic wave propagation problems: A review
Kenneth Duru, Gunilla Kreiss
It is well-known that reliable and efficient domain truncation is crucial to accurate numerical solution of most wave propagation problems. The perfectly matched layer (PML) is a m…
