Abstract : An interesting property of honeycomb cores is that their apparent Poisson's ratio may assume values from almost zero to well above one, depending upon the shape and orientation of the cells. This unusual behavior prompted this study, wherein Poisson's ratio is derived for cores with hexagonal and square cells. The ratio is then related to the stiffness of a sandwich panel containing such cores. It is shown that large variations of Poisson's ratio for honeycomb cores have little effect on the stiffness of the sandwich panel. (Author)
