Damage detection in a suspension bridge model using the interpolation damage detection method

2012
Herein the feasibility of a damage detection and localization method (the Interpolation Damage Detection Method) is investigated for damage detection of long span suspension bridges. Based on the response induced by wind loading, a 'signature' of the structure in the intact state is obtained in terms of the power spectral densities of responses along ...

Deep Network For Road Damage Detection

2020 IEEE International Conference on Big Data (Big Data), 2020
Heavy use by cars and trucks leads to huge damages, so road damage detection is an essential task to road maintenance. Traditional road damage detection has to require a huge amount of manual effort, it is therefore of great interest to propose vision-based systems that can automatically detect the road damages.

Structural Damage Detection by Genetic Algorithms

AIAA Journal, 2002
A two-stage procedure utilizing incomplete measurements to assess the location and extent of structural damage is presented. In the first stage, candidate damaged elements are identified using the residual force method. Based on a priori knowledge from the first stage, the damage extent is determined from candidate elements using a proposed ...

Structural Dynamic Identification and Damage Detection

2022
Dynamic methods are a powerful tool for studying the behaviour of existing structures and their health conditions. The practical application, however, often raises subtle questions related to the accuracy and completeness of experimental data, the complexity of the mechanical modelling and, ultimately, the inverse nature of the problems that leads to ...

Road Damage Detection Using RetinaNet

2018 IEEE International Conference on Big Data (Big Data), 2018
Road damage detection is of importance to road maintenance, which typically requires huge amount of manual efforts. In this work, we leverage deep learning models to analyze the road images to detect road damages efficiently. Specifically, we train and test different deep learning methods to identify efficient models with high accuracy.

A new approach to the detection of DNA damage

Leukemia Research, 1989
A method is described which permits the detection of damage produced in unlabeled DNA by daunorubicin, nitrogen mustard, or radiation. After exposure to one of the agents the cells are embedded in an agarose block and lysed to release the DNA. The agarose block is then transferred to a well in an agarose gel and electrophoresis performed. DNA damage is

Creep Damage Detection

2016
Creep is an important factor in designing metal structures used at elevated temperatures. Dislocations again play a key role in deformation at elevated temperatures; they multiply, slip, form voids and subgrain boundaries, and annihilate. This chapter shows that the shear wave attenuation is highly sensitive to the dislocation activity in crept metals ...

Damage in Composite Material: A Microwave Detection

Key Engineering Materials, 2014
In the field of the transport, the increase of the security rule recommends to a periodic control of the structure to detect damage due to mechanical loadings. Now, current materials, used in the case of transport applications, are the composite materials.

Wavelet-Based Structural Damage Detection

Volume 1: 21st Biennial Conference on Mechanical Vibration and Noise, Parts A, B, and C, 2007
In this paper, a new wavelet-based approach for crack identification in beam-like structures is presented and applied to simply-supported beams with single or multiple cracks. A novel damage index, based on finding the difference between two sets of detail coefficients obtained by the use of the Stationary Wavelet Transform (SWT) of two reconstructed ...

Damage Detection Through Pipe Bends

Journal of Pressure Vessel Technology, 2017
Axial pipeline defects are detectable from torsional guided wave reflections through 90 deg elbows. This paper demonstrates that detection of localized damage in carbon steel pipes with a so-called standard long and very long radius elbow is possible using a single permanently installed source–receiver pair.
