Metamaterials—engineered materials with tailored architectures—have transformed our approach to designing materials with highly specialized mechanical responses, from enhanced resilience and failure resistance to controlled deformation pathways. Yet, the fracture behavior of these materials under various loading conditions remains a critical and complex research area. This mini symposium seeks to explore advancements in computational modeling that enable the accurate prediction of fracture initiation and propagation in metamaterials, taking into account their unique microstructural architectures and nonlinear material properties. Contributions are encouraged that showcase novel computational methods, such as multiscale simulations, phase-field models, and machine-learning-assisted fracture predictions, which can handle the intricate geometries and multi-physics aspects characteristic of metamaterials.

In addition, we welcome experimental and theoretical studies that provide insight into the mechanisms of fracture at different scales and validate computational models. Topics of interest include, but are not limited to, fracture mechanics of architected materials, the interplay between microstructural design and failure modes, and advanced techniques for characterizing and simulating fracture in soft, brittle, or hybrid metamaterials. This symposium offers a platform for discussing the latest breakthroughs and fostering cross-disciplinary dialogue in pursuit of more robust, adaptable, and application-specific metamaterial designs.
