" Experimental and Numerical Evaluation of Dual-Layer Sonic Crystal Scatterers with Embedded Helmholtz Resonators"
Nicolas Herrera-Leon, Paulo Amado-Mendes, Luis Godinho

This research proposes a novel design of a sonic crystal unit cell that integrates multiple mechanisms to achieve broadband frequency attenuation. The design was numerically modeled and experimentally validated to evaluate both the absorbing material used for the scatterers and the embedded Helmholtz resonators. Results show a marked improvement in insertion loss compared with an equivalent rigid configuration, with enhanced performance before and after the band gap.

📖 “Low-cycle fatigue behaviour of AM46 carbon steel produced by wire arc additive manufacturing”
👩‍🔬👨‍🔬 David Andrade, Mariela Mendez Morales, Carlos Zhu, Kaike Monteiro, Artur Mateus, Luís Simões da Silva, Ricardo Branco
This work investigates the low-cycle fatigue behaviour and fracture mechanisms of WAAM-produced AM46 carbon steel, considering different build orientations and surface conditions.
The study provides new insights into the cyclic performance of additively manufactured steel, contributing to the development of safer, more reliable and fatigue-resistant structural components.

📢 New publication!

We are pleased to share a new paper published in Construction and Building Materials by Amin Nazerigivi, Javier Ortega Heras, Graça Vasconcelos and Hugo Rodrigues:

“Integration of NDT for the mechanical characterization of dry-joint masonry walls built with granite and schist: Field experimental validation”

The study presents an in-situ investigation of dry-joint stone masonry walls in vernacular buildings, combining visual-based masonry quality assessment with non-destructive testing techniques, including sonic pulse velocity, ultrasonic pulse velocity and Schmidt hammer rebound testing.

By focusing on granite and schist masonry, this work contributes to improving the mechanical characterization, diagnosis and conservation of traditional stone masonry heritage, supporting more informed assessment and intervention strategies.

“Durability of NSM CFRP-to-concrete bond after six years of exposure to laboratory and outdoor environments”

This study provides rare long-term experimental evidence on the durability of near-surface mounted (NSM) CFRP strengthening systems for reinforced concrete structures. The work followed specimens exposed for six years to laboratory-controlled conditions and to real outdoor environments in Portugal, including Lisbon, Serra da Estrela, Elvas, and Viana do Castelo.

The results show that CFRP laminates maintained their mechanical performance after ageing, while the epoxy adhesive was more sensitive to environmental exposure, particularly under water immersion. These findings contribute to more reliable durability assessment and long-term design of CFRP strengthening systems.

👏 Congratulations to the authors: Luís Correia, Aloys Dushimimana, Sayed Adeel Jawed, João Miguel Pereira, Susana Cabral-Fonseca, and José Sena-Cruz.
