摘要
采用状态分解-解析方法分析了蜂窝荚芯梁由于面板与芯材脱胶而引起的附加位移、附加内力与能量释放率,并讨论了未脱胶段的附加变形对脱胶段附加位移及能量释放率的影响,为简化力学模型提供了理论依据.
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.
