Time-domain numerical simulations of multiple scattering to extract elastic effective wavenumbers
Mathieu Chekroun, Loïc Le Marrec, Bruno Lombard +1
Elastic wave propagation is studied in a heterogeneous 2-D medium consisting of an elastic matrix containing randomly distributed circular elastic inclusions. The aim of this study…
Numerical modeling of transient two-dimensional viscoelastic waves
Bruno Lombard, Joël Piraux
This paper deals with the numerical modeling of transient mechanical waves in linear viscoelastic solids. Dissipation mechanisms are described using the generalized Zener model. No…
Numerical modeling of 1-D transient poroelastic waves in the low-frequency range
Guillaume Chiavassa, Bruno Lombard, Joël Piraux
Propagation of transient mechanical waves in porous media is numerically investigated in 1D. The framework is the linear Biot's model with frequency-independant coefficients. The c…
Free and smooth boundaries in 2-D finite-difference schemes for transient elastic waves
Bruno Lombard, Joël Piraux, Céline Gélis +1
A method is proposed for accurately describing arbitrary-shaped free boundaries in single-grid finite-difference schemes for elastodynamics, in a time-domain velocity-stress framew…
Numerical modeling of elastic waves across imperfect contacts
Bruno Lombard, Joël Piraux
A numerical method is described for studying how elastic waves interact with imperfect contacts such as fractures or glue layers existing between elastic solids. These contacts hav…
