Additive manufacturing introduced substructure and computational determination of metamaterials parameters by means of the asymptotic homogenization

BE Abali, E Barchiesi - Continuum Mechanics and Thermodynamics, 2021 - Springer
Metamaterials exhibit materials response deviation from conventional elasticity. This
phenomenon is captured by the generalized elasticity as a result of extending the theory at …

Appearance of the nonlinearity from the nonlocality in diffusion through multiscale fractured porous media

M Panfilov, M Rasoulzadeh - Computational Geosciences, 2013 - Springer
We shall consider diffusion or single-phase flow in a multiscale porous medium which
represents an infinite set of self-similar double-porosity media. At each scale, the medium …
