Numerical analysis of hygro-thermal behaviour and damage of concrete at high temperature
TLDR
In this article, a computational analysis of hygro-thermal and mechanical behavior of concrete structures at high temperature is presented, and the evaluation of thermal, hygral and mechanical performance of this material, including damage effects, needs the knowledge of the heat and mass transfer processes.Abstract:
A computational analysis of hygro-thermal and mechanical behaviour of concrete structures at high temperature is presented. The evaluation of thermal, hygral and mechanical performance of this material, including damage effects, needs the knowledge of the heat and mass transfer processes. These are simulated within the framework of a coupled model where non-linearities due to high temperatures are accounted for. The constitutive equations are discussed in some detail. The discretization of the governing equations is carried out by Finite Elements in space and Finite Differences in time. Copyright © 1999 John Wiley & Sons, Ltd.read more

Modelling of the drying and flooding of underground iron mines in Lorraine (France)
TL;DR: In this paper, a poroplastic model and continuous porous media were used to model the hydrous cycle imposed to the rocks in these underground deep mines, and it was shown that the final stage of resaturation induces transient tensile stresses that lead to failures at the roof and at the floor of the galleries.

Heat and Mass Transfer in Concrete at Elevated Temperature
TL;DR: In this paper, the authors presented a mathematical and computational model to simulate the coupled heat and mass transfer of concrete subjected to fire by means of the finite-volume method, considering not only the transport of water vapor and liquid water but also the evaporation of liquid water and the dehydration of bound water.
