Influence of visco-elasticity on the stress development induced by alkali-silica reaction

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

The alkali-silica reaction causes long-term degradation in the microstructure of affected concrete as well as macroscopic expansion. In this paper, a micro-mechanical model based upon an explicit representation of the microstructure has been used to simula ...

Finite elements in space and time for the analysis of generalised visco-elastic materials

Karen Scrivener, Cyrille Dunant, Alain Benjamin Giorla

Numerical analysis of linear visco-elastic materials requires robust and stable methods to integrate partial differential equations in both space and time. In this paper, symmetric space-time finite element operators are derived for the first time for elem ...

A critical comparison of several numerical methods for computing effective properties of highly heterogeneous materials

Cyrille Dunant, Alain Benjamin Giorla

Modelling transport and long-term creep in concrete materials is a difficult problem when the complexity of the microstructure is taken into account, because it is hard to predict instantaneous elastic responses. In this work, several numerical methods are ...

Modelling of Alkali-Silica Reaction under Multi-Axial Load

Alain Benjamin Giorla

Alkali-Silica Reaction (ASR) is a deleterious expansion phenomenon which affects the long-term behaviour of concrete. Its origin is a chemical reaction between amorphous silica present in the aggregates and alkali ions from the concrete pore solution. The ...
