Corrigendum to “Surface effect on the contact problem of a piezoelectric half-plane” [Int. J. Solids Struct, 185-186 (2020) 380–393]

Abstract This corrigendum corrects some errors of the paper entitled “Surface effect on the contact problem of a piezoelectric half-plane”, International Journal of Solids and Structures 185-186 (2020) 380–393 (Song et al., 2020). Because there is an error in the Fortran code when we calculate the numerical solution of the contact stress and electric displacement, their values become smaller compared to the original results. Moreover, the influencing trends of the surface effect are slightly different from the original results. However, the formulations of the original paper are intact.
