The details of a study to experimentally determine the strain and deflection profile induced in a uniformly loaded, simply supported 1.1-m x 2.3-m aluminum-skin Kraft-paper-honeycomb-core sandwich panel are documented. Twelve panels typical of the type used in military rigid wall tactical shelters were tested at loadings up to 70 kPa. The experimental procedure and apparatus, including a special vacuum chamber constructed to stress the large panels, are described as well as details of the various panels tested. the effects of loading arrangement, strain gage transverse sensitivity and adhesive joint location are addressed. Panel strain and deflection data and core shear data are presented.
