Aluminum alloy sheet and plate are commonly used in automobile, train, aircraft and so on where lightweight is required. However, lower costs and lighter weight materials are demanded. In order to satisfy the demand for lightweight without changing the material, it is necessary to raise the second moment of area to increase the bending stiffness. The purpose of this study is creating isotropic patterned shell structures to increase the bending stiffness of aluminum alloy sheet and plate. In this paper, patterned shell structures which have the large second moment of area in arbitrary cross sectional dimensions were developed. FEM results and experimental results indicated that the developed patterns reduce by half the weight of sheets under equivalent bending stiffness condition.
