| 内容記述 | A new form of sandwich core of high strength created by a topological transformation of a single plane is proposed herein. The resultant core is to be manufactured from a single sheet through a plastic forming. The purpose of this proposition is to present a sandwich core which has following principal characteristics; simplicity of form, applicability to both flat and curved sandwiches, possibility of circulating fluid between facings, the easiness of manufacture, the adaptability to large as well as small scale core, and the isotropy or controllable orthotropy of shear modulus. This core, designated as zeta-core by this author, is a sophisticated shell structure whose mid-surface is characterized by a doubly corrugated surface combining a couple of facings. An elementary analysis proves that the directional mean of shear modulus of zeta-core can compete with that of honeycomb core of identical apparent density, and that it is possible to design zeta-core of any orthotropy including, of course, isotropy in shear modulus. As for the realization aspect, no essential difficulty was encountered in trial manufacture of zeta-core from aluminum, plastics, and G.R.P. sheet materials. Furthermore, it can be predicted that the cost of production of zeta-core is relatively low in comparison with honeycomb core. It seems probable that the introduction of zeta-core of high shear modulus which can be made of various engineering materials will open up fresh possibilities for structural sandwich construction. | |||||||
