As one of the nicest theoretical techniques available for dealing with severely disordered systems and stochastic-geometry situations, percolation theory provides a well-defined, transparent, and intuitively satisfying model for spatially random processes, which is widely used for illustrating phase transitions and critical phenomena. This paper introduces percolation theory briefly, and reviews the applications of percolation model in computational materials science, especially new progress of percolation study on de-alloying corrosion, colossal magnetoresistance materials, gate dielectrics breakdown and electric conduction composites.
