Multi-scale prediction of chemo-mechanical properties of concrete materials through asymptotic homogenization

E Bosco, R Claessens, ASJ Suiker - Cement and Concrete Research, 2020 - Elsevier
In the present contribution, the effective mechanical, diffusive, and chemo-expansive
properties of concrete are computed from a multi-scale and multi-physics approach. The …

A multiscale method to calculate filter blockage

MP Dalwadi, M Bruna, IM Griffiths - Journal of Fluid Mechanics, 2016 - cambridge.org
Filters that act by adsorbing contaminant onto their pore walls will experience a decrease in
porosity over time, and may eventually block. As adsorption will generally be greater …

Sulfate attack in sewer pipes: Derivation of a concrete corrosion model via two-scale convergence

T Fatima, A Muntean - Nonlinear Analysis: Real World Applications, 2014 - Elsevier
We explore the homogenization limit and rigorously derive upscaled equations for a
microscopic reaction–diffusion system modeling sulfate corrosion in sewer pipes made of …

Homogenisation of a locally periodic medium with areas of low and high diffusivity

TL van Noorden, A Muntean - European Journal of Applied …, 2011 - cambridge.org
We aim at understanding transport in porous materials consisting of regions with both high
and low diffusivities. We apply a formal homogenisation procedure to the case where the …
