A sandwich structure is defined by a bi-geometrical structure and substructure related by the modulus of residual stiffness, . These two geometries interact with each other to modify the response of the whole. This parametric study of the modulus of residual stiffness derives for a range of 10 core materials used in the marine, aerospace, and construction industries, each core bonded to a range of one to seven skin layers. Test results for measured and predicted show consistently good correlation for the current database 2000, and for results measured in 1995, 1997, and 1998. The predicted results are used in the COREDES (Engi, Inc., North Fort Myers, FL) structural beam equations, which calculate the loads, deflection, stress, and the bilinear elastic curve for structural sandwich panels. The correlation to three-beam test data results is very good overall for one- to three-layer fiberglass skins on a standard thickness core, and these results clearly show has no effect on predictive results above five skin layers. The excellent correlation of these plotted comparisons of predictive data to test data indicates that this modulus is an important governing factor in the response of sandwich beams.
