Abstract

In this paper, the mechanism of stress concentration due to defects in honeycomb sandwich structure is studied by using finite element method. It is found that the stress concentrantion can be expressed as a function of E _ct_c/E_pt_p, where t_c and t_p are the thickness of core and plate, respectively, and E _c and E_p are the Young's modulus of core and plate, respectively. Also, it is found that the stress concentrantion can be evaluated by an approximation of an elliptical inclusion. The validly of this technique is verified through comparison of the evaluation values with the numerical results obtained by FEM.
