Journal ArticleDOI
Review of pore network modelling of porous media: Experimental characterisations, network constructions and applications to reactive transport
TL;DR: Pore network models are found to be a valuable tool for understanding and predicting meso-scale phenomena, linking single pore processes, where other techniques are more accurate, and the homogenised continuum porous media, used by engineering community.
Journal ArticleDOI
Monte Carlo simulations of mesoscale fracture modelling of concrete with random aggregates and pores
TL;DR: In this paper, a procedure for generating two-dimensional heterogeneous meso-scale concrete samples is developed, in which the multi-phasic features including the shape, size, volume fraction and spatial distribution of aggregates and pores are randomised.
Journal ArticleDOI
Computational technology for analysis of 3D meso-structure effects on damage and failure of concrete
TL;DR: In this paper, an efficient algorithm for particle generation and packing is proposed to represent 3D meso-structures as collections of discrete features distributed randomly in a continuous phase, where the continuous phase represents mortar, while the features are aggregates and voids.
Journal ArticleDOI
Monte Carlo Simulations of Mesoscale Fracture of Concrete with Random Aggregates and Pores: a Size Effect Study
TL;DR: In this article, Monte Carlo simulations of mesoscale finite element models containing random inclusions (aggregates and pores) with prescribed volume fractions, shapes and size distributions (called meso-structure controls) are studied.

TL;DR: In this article, three dimensional X-ray tomographic images of intergranular stress corrosion crack nucleation and growth in sensitised austenitic stainless steel provide evidence for the development of crack bridging ligaments, caused by the resistance of non-sensitised special grain boundaries.
