Damage Assessment Using the Auto-Correlation-Function-Based Damage Index
The International Journal of Acoustics and Vibration, 2023A damage index describing damage severity based on the Auto correlation function at Maximum point value Vector (AMV) is proposed for damage assessment as well as locating the damage is described in this study. The detectability of the AMV-based damage detection method is compared with Mean Strain Energy (MSE) and the Generalized Flexibility Matrix (GFM)

Natural Hazards, 2003
A new damage index to estimate damage to buildings relies on construction costs per square metre, and a replacement ratio which approximates costs relative to the cost of replacing a median-sized family home. Building damage is estimated against a five-point scale with Central Damage Values at 0.02, 0.1, 0.4, 0.75 and 1.0 of the replacement cost ...

Stylus damage prevention index
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000Stylus methods for measuring surfaces have sometimes been blamed for causing damage to the surface because of the stylus pressure. This paper investigates this possibility and develops a ‘potential damage index’ which takes into account the instrument parameters, static and dynamic, and surface parameters.

Seismic Damage Estimation Index for Service Lines
IEEJ Transactions on Electronics, Information and Systems, 2011AbstractThe purpose of this paper is to propose a new index for the seismic damage estimation of service lines. The proposed index is based on the tension of each service line due to an earthquake event. Because the tension is evaluated using not only the seismic intensity, but also the dynamic properties of the major components of the distribution ...

A New Damage Index for Isolated Structures
International Journal of Structural Stability and Dynamics, 2019Damage indices based on structural dynamic characteristics are often used to detect damage in the structures. In this study, a new index for identifying damages in base-isolated structures is proposed using the frequency response function (FRF).

Developing a hurricane damage index
2010Accurate information on damage caused by landfalling hurricanes benefits decision making and response of groups such as emergency managers and insurance companies. Estimates of potential damage made in advance of landfall using readily available storm information would provide useful guidance for preparations and rapid response.

A new flexibility-based damage index for structural damage detection
Smart Materials and Structures, 2013A new flexibility-based damage index has been proposed for structural damage detection. It is derived from the strain energy theory that the ratio of the flexural stiffness of the structure before and after damage is a function of the uniform load surface (ULS) curvature.

A damage index of generalised applicability
Engineering Structures, 2005Abstract Structural damage caused by earthquakes may be due to excessive deformations, or it may be in the form of accumulated damage sustained under repeated load reversals. The way these two components are combined is strictly dependent upon the structural material.

Pulsatility Index, Patent Ductus Arteriosus, and Brain Damage
Pediatrics, 1982The study of CBF velocity by external Doppler method appears to offer the clinician a noninvasive tool with which to gather information related to changes in cerebral hemodynamics. Inasmuch as the clinical condition of sick preemature infants is different from that of adults with obstructive vascular disease, and as the arteries under study are deeper ...

Refractive-index dependence of pulsed-laser-induced damage
Optics Letters, 1979A parametric study of the threshold for pulsed-laser-induced damage with refractive index for surfaces and thin films of several transparent optical materials is reported. An empirical analysis of the experimental results obtained using 1.06-μm radiation in ~40-nsec pulses, together with other published data, yields, to first order, a 1/(n2 − 1 ...
