Second Generation of Active Structural Control in Civil Engineering

open access: yesComputer-Aided Civil and Infrastructure Engineering, 1996
: Research and development in active control of civil engineering structures in the United States has approximately a 20-year history. Under the leadership of the U.S. National Science Foundation in forming the U.S. Panel on Structural Control Research and in launching a program initiative in the area of structural control, there has been a surge of ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

open access: yesAdvanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Analysis and Comparison of the Infrastructure Report Cards as a Decision Making Tool for Sustainable Development

open access: yesBuildings, 2023
Infrastructure plays a pivotal role in a nation’s economic and societal progress. However, due to the substantial expenses and the constraints of a limited government budget, the need to assess the condition of each infrastructure and identify those ...

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Sub‐Nanometer Curvature Unlocks Quantum Orbital Flexoelectricity in Graphene

open access: yesAdvanced Materials, EarlyView.
In self‐assembled, reproducible, large‐area, quasi‐pristine graphene nanowrinkles, extreme curvature forces out‐of‐plane π‐electrons toward hybridization, driving a transition from classical to quantum orbital flexoelectricity. As curvature approaches the fundamental physical limit set by the C─C bond length, the resulting polarization increases by ...
