Sensor placement with optimal damage detectability for statistical damage detection

open access: yesMechanical Systems and Signal Processing, 2022
Damage diagnosis based on global structural vibrations critically depends on the sensor layout, in particular when a small number of sensors is used for large structures under unknown excitation. This paper proposes a sensor placement strategy that yields an optimized sensor layout with maximum damage detectability in selected structural components ...

Damage Detection with Auxiliary Subsystem [PDF]

open access: yesAdvances in Science and Technology, 2008
Among Non-Destructive Evaluation, vibration-based methods respond to the current ten- dency which is to integrate into the structure identication and monitoring systems; to this aim transducers and sensors are embedded with the mechanical system and driven by suitably designed electronic controllers.

Broad spectrum detection of DNA damage by Repair Assisted Damage Detection (RADD) [PDF]

open access: yesDNA Repair, 2018
Environmental exposures, reactive by-products of cellular metabolism, and spontaneous deamination events result in a spectrum of DNA adducts that if un-repaired threaten genomic integrity by inducing mutations, increasing instability, and contributing to the initiation and progression of cancer.

An investigation on vibration-based damage detection in circular plates [PDF]

open access: yes, 2009
This study aims at the development of vibration-based health monitoring (VHM) methodology for thin circular plates. The possibility of using the first several natural frequencies of a circular plate for damage detection purposes is investigated first ...

Fatigue Crack Monitoring of T-Type Joints in Steel Offshore Oil and Gas Jacket Platform

open access: yesSensors, 2021
Several approaches have been used in the past to predict fatigue crack growth rates in T-joints of the offshore structures, but there are relatively few cases of applying structural health monitoring during the non-destructive testing of jacket platforms.

Bridge damage detection based on vibration data: past and new developments [PDF]

open access: yes, 2017
Overtime, bridge condition declines due to a number of degradation processes such as creep, corrosion, and cyclic loading, among others. Traditionally, vibration-based damage detection techniques in bridges have focused on monitoring changes to modal ...

Damage Detection of Axially Loaded Beam: A Frequency-Based Method [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2016
The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack ...
