摘要：

A new method for maximizing stiffness per unit weight in sandwich beams with foam cores is described. Optimum values of core thickness, face thickness and core density are obtained from the analysis. Measurements of the stiffness per unit weight have been made on sandwiches with foamed polyurethane cores. The theoretical analysis is in good agreement with the results of these tests.
