Composite Pentamode Metamaterials for Enhanced Wave Manipulation by Asymmetric Surface Structure
The asymmetric pentamode surface structure can reduce the scattering from 26.3 dB to 0.96 dB and multiply the frequency range of wave manipulation. This approach results in a 95% improvement in compressive strength compared to pentamode structures with the same acoustic performance, enabling wider deepwater applications.

Recent advances in embedded technologies and self‐sensing concrete for structural health monitoring
Abstract Fully embedded and spatially diffuse sensors are central to the advancement of civil and construction engineering. Indeed, they serve as an enabling technology necessary for addressing the current challenges associated with through‐life management and structural health monitoring of existing structures and infrastructures. The need to identify

Influence of environmental conditions on the creep behavior of large‐scale concrete specimens
Abstract In this article, a testing campaign on large‐scale concrete specimens to study the influence of environmental conditions on their creep behavior for different member sizes is presented. This testing campaign is unique due to its specimen dimensions (cross‐sectional areas of up to 1 m2) and the continuous deformation measurements for over 6 ...

Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

Abstract To investigate crack development, in particular the evolution of crack widths and crack spacing during the crack formation and stabilized cracking stage, an experimental campaign on reinforced concrete slabs under uniaxial tensile loading was conducted. The specimens were, prior to the campaign, subjected to restraint‐induced stress for 7 days,
