Thermo-elastic-plastic porous material undergoing thermal loading

摘要

A model for predicting elastic-plastic stresses within a surface-heated porous structure has been developed. The relevant phenomena for the moisture, pressure, temperature and displacement fields in thermoelastic-plastic porous material are anlaysed. Considering mass and energy transfer processes, a set of governing differential equations is presented. The solution of the problem has been obtained with a finite difference scheme. The results demonstrate the influence of the evaporation mechanism on pressure and thermal stresses within the porous material.
