Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) aim to accelerate discovery, developing, manufacturing, and deploying of advanced materials. However, it is often not the material performance, but the structural performance or rather system performance we are after. To fill the gap between materials genome and structural analysis, a new concept, Structure Genome (SG) is proposed. SG is the smallest mathematical building block connecting materials and structures and contains all the constitutive information needed for a structure. The Mechanics of Structure Genome (MSG) represents a revolutionary approach to multiscale modeling drastically different from the conventional bottom-up multiscale modeling approaches. The principle of minimum information loss (PMIL) is used to avoid a priori assumptions commonly invoked in other approaches. MSG confines all approximations to the constitutive modeling for all types of structures including 3D solids, 2D plates/shells, and 1D beams, directly linking the structural properties with microstructural details. MSG simplifies multiscale constitutive modelling to answer three fundamental questions: 1) what is the original model needed for capturing relevant physics? 2) what is the model wanted for a particular design? 3) what is the SG? MSG allows one to choose the starting scale and ending scale and capture details as needed and affordable without invalid scale separation and assumptions within scales. A companion code called SwiftComp is developed as a general-purpose constitutive modeling software which can be used by itself for virtual testing of structures and materials or as a plugin for conventional finite element software packages such as Abaqus, Ansys, Nastran with efficient high-fidelity multiscale constitutive modeling capabilities. SG concept is applicable to any structures and materials featuring heterogeneity and anisotropy including but not limited to composite materials, 3D printed materials, metamaterials, biomaterials, auxetic materials, smart materials, soft materials, etc.
