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

Non-local modelling of cyclic thermal shock damage including parameter estimation
TL;DR: In this article, rate dependent evolution laws are identified and characterized to model the mechanical and thermal damage occurring in coarse grain refractory material subject to cyclic thermal shock, where the interacting mechanisms for elastic deformation driven damage induced by temperature gradients and thermal damages induced by isotropic thermal expansion are combined and represented by a single variable for the total damage.
