“…To determine which kind of microstructure is suitable for every element, multiple kinds of topological variables relating to every element are introduced to seek out the optimized macroscopic topology and rational layout of various lattice microstructures. The volume and stiffness matrix of the i -th element in a three-phase domain (two different constituent materials and one void phase) can be identified using various filter functions [ 56 ] as follows: where and are the first and second kinds of topological variables with regard to the i -th element, respectively; and respectively represent the intrinsic volumes of the first and second kinds of microstructure elements; and indicate the intrinsic stiffness matrices of the first and second kinds of microstructure elements, respectively; and are the first and second volume filter functions, respectively; and and are the first and second stiffness matrix filter functions, respectively. Based on Equations (3) and (4), it can be apparently seen that the first kind confirms the macroscale structure (with or without material), while the second kind recognizes the designated material for every retained element.…”

“…Topology optimization may greatly enhance the performances of materials and structures for many engineering applications. It has been exhaustively studied, and various topology optimization methods have been developed over the past few decades, e.g., the solid isotropic material with penalization (SIMP) method [17], evolutionary structural optimization (ESO) method [18], bi-directional evolutionary structural optimization (BESO) method [19,20], moving morphable component (MMC) method [21], feature-drive method [22,23], level set method [24,25], independent continuous mapping (ICM) method [26], and feasible domain adjustment topology optimization method [27].…”
