    Abstract
  • A state decomposition analytical method is proposed for analysis of additional displacements,additional internal forces and energy release rate produced by debonding between face plate and core material of a honeycomb sandwich beam.Then the influences to the odditional displacement and energy release rate given by the core deformation of the undebonded beam segment are discussed.Finally,a simplified mechanical model is prosvided for debonding analysis.
