Propagation of elastic waves through textured polycrystals: application to ice
(Royal Society Publishing, 2015)
The propagation of elastic waves in polycrystals is
revisited, with an emphasis on configurations relevant
to the study of ice. Randomly oriented hexagonal
single crystals are considered with specific, nonuniform,
probability ...
Propagation of elastic waves through polycrystals: the effects of scattering from dislocation arrays
(2006)
We address the problem of an elastic wave coherently propagating through a two-dimensional polycrystal. The main source of scattering is taken to be the interaction with grain boundaries that are in turn modelled as line ...
Multiple scattering from assemblies of dislocation walls in three dimensions. Application to propagation in polycrystals
(2007)
The attenuation of ultrasound in polycrystalline materials is modeled with grain boundaries considered as arrays of dislocation segments, a model valid for low angle mismatches. The polycrystal is thus studied as a continuous ...
Bounds on the hydrostatic plastic strength of voided polycrystals and implications for linear-comparison homogenization techniquesBornes de la résistance plastique hydrostatique des polycrystaux poreux et leurs implications sur des techniques basées sur des milieux linéaires de comparaison
(Elsevier France-editions Scientifiques Medicales Elsevier, 2014-01)
A linear-comparison homogenization technique and its relaxed version are used to compute bounds of the Hashin–Shtrikman and the self-consistent types for the hydrostatic strength of ideally plastic voided polycrystals. ...
Analytical expressions to estimate the effective piezoelectric tensor of a textured polycrystal for any crystal symmetry
(Elsevier Science, 2020-12)
This work introduces a set of analytical expressions that simplifies the procedure of obtaining closed-form formulas to estimate the effective piezoelectric properties of polycrystalline aggregates formed by crystals of ...
