Artificial Intelligence, Machine Learning and Smart Technologies for Nondestructive Evaluation

open access: yesSensors, 2022
Nondestructive evaluation (NDE) techniques are used in many industries to evaluate the properties of components and inspect for flaws and anomalies in structures without altering the part’s integrity or causing damage to the component being tested.

Assessment of material property variations with resonant ultrasound spectroscopy (RUS) when using additive manufacturing to print over existing parts

open access: yesJournal of Advanced Joining Processes, 2022
Additive manufacturing (AM) opens up many opportunities for repair and feature enhancement of existing components by 3D printing over already existing structures. However, much research, on the irregularities in the microstructure and lack of consistency

The monotonic behaviour of a low- to medium-density chalk through in-situ and laboratory characterisation [PDF]

open access: yesE3S Web of Conferences
Chalk is a highly variable cemented biomicrite limestone that can show widely different rock strengths and patterns of micro to macro fissuring and jointing, due to variations in depositional environments and local geological histories.

Evaluation of Stiffness and Dynamic Properties of a Mine Shaft Steelwork Structure through In Situ Tests and Numerical Simulations

open access: yesEnergies, 2021
A mine shaft steelwork is a three-dimensional frame that directs the vertical motion of conveyances in mine shafts. Here, we conduct field and numerical investigations on the stiffness and dynamic properties of these structures.
