【正文】 insulation and so on. Because of these advantages, metal honeyb sandwich panel is more and more widely used in rockets, satellites, aircraft and other aerospace applications. However, some defects with different types, shapes or sizes with occur in its preparation and service, and these defects have a negative impact on mechanical properties. But, metal honeyb sandwich panel with defects meets the performance requirements. Thus, it is of great importance to assess the ability of constant service for the metal honeyb sandwich panel. The paper gives the effect of different ratio between core missing and different dimension of surfacecore connecting defect on the mechanical properties of sandwich structure. The aim of this paper is achieved by means of numerical simulation and theoretical analysis second chapter of this paper gives the numerical simulation results under the stretching and the pressing tests for this structure with part of the core miss
