We realize an elastic second-order topological insulator hosting bothone-dimensional gapped edge states and zero-dimensional in-gap corner modes inthe double-sided pillared phononic crystal plates with square lattice. Changingthe width of two neighbor pillars breaks the inversion symmetry and induces theband inversion to emulate the quantum spin Hall effect where the gapless edgestates are obtained. Further breaking the space-symmetry at interface, thegapless edge states are gapped and inducing the edge topological transitionsand then giving rise to the zero-dimensional in-gap corner modes. Our workoffers a novel way for elastic wave trapping and robustly guiding.
