Nonlinear harmonic identification of breathing cracks in beams

•A method for the identification of breathing cracks in beams is detailed through FE simulation.•Sub- and super-harmonics of the dynamic response are used as damage indicators.•The method is effective for very small cracks.•The performance is improved by considering several modes with different moda...
