Modeling stress evolution in porous ceramics subjected to molten silicate infiltration and corrosion

•A model of corrosion failure in porous ceramics is proposed.•The coupled effects of infiltration, corrosion, and deformation are considered.•The corrosion process and delamination mechanism of TBCs are successfully predicted.•Cracks tend to initiate from the side edges of TBCs columns at the infilt...
