Abstract
High temperatures and other severe thermal conditions cause release of significant amounts of water in porous materials, and induce pore pressure and temperature gradients under which water is transported through pores. A mathematical model that simulates the coupled heat and mass transfer in heated porous media as well as the resulting stress are discussed. A finite element analysis for the solution of such a model is developed and used to study the temperature and pore pressure distribution and the resulting stresses. A comparison of predicted temperature distribution with experimental data is made, and sensitivity of the coefficient of shrinkage on the induced stress is investigated.
