A penny-shaped crack in a piezoelectric layer sandwiched between two elastic layers with the electrical saturation and mechanical yielding zones

•We simplify the mixed boundary value problem into coupling Fredholm integral equations of the second kind by Copson method.•The problem is solved in the real domain by constructing real fundamental solutions.•The numerical solutions for any layer-thickness are derived with appropriate formula deriv...
