Since the early 1980s, the U.S. Navy, in conjunction with industry, has continued to develop and test innovative lightweight structural concepts with the purpose of seeking alternative replacements for conventional plate beam metallic structures. One commercially available concept currently under investigation is lightweight metallic corrugated core sandwich panels. This paper presents both elastic and plastic design methods for lightweight metallic corrugated core sandwich panels subjected to air blast loading. The equations presented in this paper, while not a complete solution to the complicated dynamic, elastic plastic phenomena of blast wave‐rigid body interaction, are offered as a set of relatively simple analytical expressions that can be used in preliminary design. Because of the closed form nature of the equations the designer has the capability to quickly identify the most important parameters effecting the response of lightweight metallic corrugated core sandwich panels to air blast loads.
