A novel single-domain Ritz approach is presented for the free vibration analysis of cylindrical laminated shells with cut-outs. The characteristic matrices of the resolving algebraic system are computed using a special integration technique based on the implicit description of the cut-out via level set function. Validation results and studies show the potential of the method for aerospace applications.
