Efficient Model Order Reduction of Structural Dynamic Systems with Local Nonlinearities under Periodic Motion
In many nonlinear structural systems, compared with the local regions with induced nonlinear effects, the main portions of the structures are linear. An exact condensation technique based on the harmonic balance method (HBM) in conjunction with the modal expansion technique is employed to convert th...
