Nano magnetic composite is a kind of heterogeneous material. Scientists found the symmetrical and dual symmetrical phenomena in its structure previously and we find the generalized dual symmetry mechanical performance in Nano Magnetic Composite and further establish the theory. The applicable nano magnetic composite structure is analyzed thoroughly and systematically. Such phenomena as serration and step dispersing distribution of bending stress and mirror reflection of interlaminar stress are thus found. Therefore, starting from the physical features of materials, Nano Magnetic Composite are analyzed on the basis of the understanding and application of the generalized dual symmetry mechanical performance. In addition, the design parameter is optimized to attain the goal of maximizing the use of materials, which is quite meaningful.
