The oscillation properties of a laminate structure yields information about its structural integrity. Unilateral constraints and impacts dominate the oscillation properties of delaminated structures. These phenomena give rise to a nonlinear system response, whereas the degree of the nonlinearity augments with increasing intensity of excitation. The distribution of the nonlinearity on various test points allows the localisation of a delamination, exemplarily shown here on a laminated beam with a surface delamination.
