The introductory and more elementary ideas and results of micromechanics of
heterogeneous media are collected in the survey. The central problem under discussion is …

Methods of probability theory and statistics are applied to the elasticity of polycrystals. Other
properties of polycrystals can be treated in an analogous manner. Statistics permits us to …

This paper is concerned with two multi-mechanism based models for application to
ratchetting effect. The 2M1C (2 Mechanisms and 1 Criterion) model and 2M2C (2 …

Prévoir le comportement de matéiaux hétérogènes aléatoires en fonction de la répartition
spatiale des constituants reste un problème largement ouvert, dont on expose les enjeux, le …

Utilizing statistical methods known from linear elasticity it is shown how effective 3rd (and
higher) order elastic constants (TOEC) of micro-heterogeneous media can be calculated …

Propagation of uniaxial sound waves in heterogeneous linear elastic one-dimensional
media is considered. The scalar wave equation is transformed by the Liouville substitution …

Wave propagation in complex engineering structures is addressed. Particular attention is
paid to modelling of such intrinsic properties of complex structures as parameter uncertainty …

Propagation of sound waves in heterogeneous linear elastic solids and ideal compressible
fluids is considered for the case of rapid fluctuations of their material parameters. The scalar …

Propagation of elastic waves in heterogeneous linear 1-D media is considered. The scalar
wave equation is transformed by the Liouville substitution and the Dyson integral equation is …
