摘要
The ways to identify the equivalent transverse shear modulus of the honeycomb core are presented. G yz is identified with a model of trident core cell, G xz is computed using a model of two walled core cells by boundary element method. The shear deformations of the cells are simplified to plane stress problems related on the boundary of the cell walls. Coupled boundary element equations for the plane pairs are established, and numerical examples show that this simple efficient 2 D model has comparable accuracy with that of three dimensional finite element model.
