Brief description:

This research develops a multiscale modeling framework for asymmetric auxetic metamaterials, which exhibit exceptional energy absorption and mechanical performance but are not well captured by conventional approaches. The study introduces a novel formulation to represent non-symmetric periodicity and integrates it with computational homogenization to uncover microstructure–property relationships. The resulting data is leveraged to build an AI-based predictive model for efficient material behavior estimation. Ultimately, this work enables the optimized design of high-performance auxetic structures, with potential applications in advanced engineering systems such as aerospace and protective structures.
