Hierarchical Granular Metamaterials
James Utama Surjadi, Bastien F. G. Aymon, Ayan Kumar +4
Granular materials dissipate energy efficiently through intergranular interactions, yet their disordered, dense nature precludes precise control and integration into lightweight sy…
Enhanced Impact Mitigation via 3D-Multilayered Material Architectures
Thomas Butruille, Joshua C. Crone, Carlos M. Portela
Materials designed by nature commonly exhibit functional grading and laminated structures, particularly when intended for enhanced impact protection. Synthetic materials have also…
Dynamic Mechanical Response of Spinodal Architectures Across Length and Time Scales
Vatsa Gandhi, Rishi Kommalapati, Carlos M. Portela +1
High-throughput characterization of architected materials across a wide range of length scales enables rapid screening of topologies for engineering applications. Scaled-down speci…
Mechanics of three-dimensional micro-architected interpenetrating phase composites
Andrew Y. Chen, Carlos M. Portela
Composite materials are used across engineering applications for their superior mechanical performance, a result of efficient load transfer between the structure and matrix phases.…
Curvature-Guided Mechanics and Design of Spinodal and Shell-Based Architected Materials
Somayajulu Dhulipala, Carlos M. Portela
Additively manufactured (AM) architected materials have enabled unprecedented control over mechanical properties of engineered materials. While lattice architectures have played a…
