A kind of defect with some of the cell walls missing in a honeycomb structure causes the loss of continuum of the honeycomb, and thus results in the stress concentration around the defect tip. Combined with the finite element and the analytic methods, this paper analyzed the normal stresses distribution on the cell wall at the defect tip in meso-scale. The finite element results of the tensile stress of the cell walls are obtained first. The results shows that the
