Ultrasonic wave methods constitute the leading physical mechanism for nondestructive
evaluation (NDE) and structural health monitoring (SHM) of solid composite materials, such …

Abstract Three-dimensional (3D) elastic wave simulations can be used to investigate and
optimize nondestructive evaluation (NDE) and structural health monitoring (SHM) ultrasonic …

This research focused on the elaboration of geopolymers based on natural Moroccan perlite
at room temperature by adding calcined Moroccan kaolinic clay as a source of reactive …

Surface-breaking cracks in concrete pose a significant threat to the durability of built
structures. They create pathways for an accelerated moisture intrusion, and the transport of …

The effect of the Interfacial Transition Zone (ITZ) on ultrasonic wave attenuation and velocity
in concrete is investigated in this study. These two parameters are often used to characterize …

Cracks are common defects in aluminum plate-like components that are in widespread use
in aerospace, shipbuilding, and other industries. Ultrasonic detection using Lamb waves has …

Ultrasound numerical simulation can be used as a powerful tool to investigate the
generation, propagation, and interaction of elastic waves in solid materials for non …

The multimodal characteristic of Lamb waves makes the interpretation of Lamb wave signals
difficult in either the time or frequency domain. In this work, we present our study of Lamb …

Pre-embedded grouting sleeve in prefabricated shear walls is an effective solution for the
longitudinal reinforcement connection issue. However, the compactness of grouting material …

Several non-destructive evaluation techniques to characterize concrete structures are based
on ultrasonic wave propagation. The interpretation of the results is often limited by the …
