Abstract Probability of detection (POD) as a metric for quantifying the capability inspection procedures in nondestructive evaluation (NDE), has been applied and evolved industries since 1970s. Progress had noted when certain statistical functions were brought up to model POD behavior, including log-normal (also referred Probit model). This concluded be best fit therefore widely used many studi...

Ferromagnetic materials are widely used in infrastructure, such as steam generators, storage tanks, and gas pipelines. During their service time, ferromagnetic subject to deterioration defects prone generate which could damage infrastructures cause catastrophic accidents. Magnetic flux leakage (MFL) is one of the nondestructive evaluation (NDE) methods detect characterize ensure infrastructure ...

In this paper we describe the development and application of a novel approach to fast nondestructive evaluation (NDE) via direct estimation of signi cant features from tomographic data without image reconstruction. Classically, the term tomographic has been used to refer only to X-ray, and perhaps magnetic resonance techniques, but in our framework we point out that it has been recently shown t...

This paper presents the feasibility of utilizing fiber Bragg grating (FBG) and long-period fiber grating (LPFG) sensors for nondestructive evaluation (NDE) of infrastructures using Portland cement concretes and asphalt mixtures for temperature, strain, and liquid-level monitoring. The use of hybrid FBG and LPFG sensors is aimed at utilizing the advantages of two kinds of fiber grating to implem...

In this paper we review the state of the art in an emerging new technology: embedded ultrasonic non-destructive evaluation (NDE). Embedded ultrasonic NDE permits active structural health monitoring, i.e. the on-demand interrogation of the structure to determine its current state of structural health. The enabling element of embedded ultrasonic NDE is the piezoelectric wafer active sensor (PWAS)...

In recent years, Non-Destructive Evaluation (NDE) has trended toward increased automation in data acquisition. Automated scanning has the potential to greatly increase reliability of the NDE results, but it also tends to increase the volume of data that must be inspected manually by a skilled technician. This is a time-consuming task made tedious by the fact that most of the data contains no in...

In the first and second stage nuclear program of Department of Atomic Energy (DAE), technologies are matured for Pressurised Heavy Water Reactors (PHWRs) and Sodium-Cooled Fast Breeder Reactors (FBRs). Pre-service-Inspection (PSI), In-Service-Inspection (ISI) and Post-Irradiation-Examination (PIE) procedures are carried out for mechanical components and structures/assemblies of these reactors, ...

Ultrasonic damage detection and characterization is commonly used in nondestructive evaluation (NDE) of aerospace composite components. In recent years there has been an increased development of guided wave based methods. In real materials and structures, these dispersive waves result in complicated behavior in the presence of complex damage scenarios. Model-based characterization methods utili...

This paper discusses the development of a methodology for multi-scale multi-domain predictive simulation of structural sensing. Tools are provided to extend the modeling capacities and improve quality and reliability of 1-D and 2-D guided wave propagation models using commercially available finite element method (FEM) packages. Predictive simulation of ultrasonic nondestructive evaluation (NDE)...

Detection of precursor damage followed by the quantification of the degraded material properties could lead to more accurate progressive failure models for composite materials. However, such information is not readily available. In composite materials, the precursor damages-for example matrix cracking, microcracks, voids, interlaminar pre-delamination crack joining matrix cracks, fiber micro-bu...
