摘要：
In this work a model of a layered composite beam and plate with a single delamination failure is presented. Undamaged parts of the beam and plate are modeled by finite elements while the delamination is substituted by special boundary conditions. The elaborated model can be applied for the analysis of the influence of the delamination length and location on changes in bending natural frequencies and mode shapes of laminated composite beams and plates. Information about dynamic behavior of delaminated composite beams and plates received from the elaborated models can be used in diagnostic systems based on vibration measurements.
