The problem of beam-plates with a delamiuation located at an arbitrary site undergoing non-linear free vibration without damp is investigated.For this problem,nonlinear governing equations as well asthe continuity,equilibrium and compatibility conditions are established.The Galerkin method and harmonicbalance method are employed to find solutions.Finally,in some examples,amplitude-frequency curves ofthe delaminated structure are presented in order to reveal some special dynamic features.
