【Abstract】 A unit cell model of the orthogonal and diagonal grid is set up, and the plane grid structure is considered as a continuum membrane. Based on the equivalence rule of energy, the constitutive parameters of the membrane are obtained. A type of composite is formed by embedding the grid structure in isotropic matrix, and the constitutive parameters of the 2-dimensional composite material are given as well. All these formulae for obtaining the constitutive parameters are verified numerically.更多还原
