Representative Structural Element - A New Paradigm for Multi-Scale Structural Modeling
Abstract
Under the sponsorship of AFOSR, we have successfully achieved the objective to establish a new paradigm for multiscale structural modeling to provide a systematic approach for efficient high-fidelity modeling of aerospace structures featuring multiscale heterogeneities and anisotropy. The proposed approach uses the concept of representative structural element, later renamed to be structure genome (SG) to emphasize the potential of this concept to bridge materials genome and structural analysis, and to better align with the Materials Genome Initiative (MGI). In this project, we have formulated the general theory for mechanics of structure genome (MSG), carried out a critical assessment of the proposed approach, and applied this approach to predict static failure and imperfect interfaces, construct models for hyperelastic materials, elastoplastic materials, viscoplastic materials, damaged materials, smart laminates, aperiodic materials, and last but not least, applied this approach to create new theories for laminates and micromechanics, and to provide a versatile solution for general free-edge stress problems.
