The use of Statistical Methods in Mechanical Engineering

Statistics is an important tool to handle the vast data of present era as statistics can interpret all the information in such a beauty that so many conclusions can be extracted from it. The aim of this study is to see the use of statistical methods in Mechanical Engineering (ME) therefore; we selected research papers published in 2010 from the well reputed journals in ME under Taylor and Francis Company LTD. More than 350 research papers were downloaded from well reputed ME journals such as Inverse Problem in Science and Engineering (IPSE), Machining Science and Technology (MST), Materials and Manufacturing Processes (MMP), Particulate Science and Technology (PST) and Research in Nondestructive Evaluation (RNE). We recorded the statistical techniques/methods used in each research paper. In this study, we presented frequency distribution of descriptive statistics and advance level statistical methods used in five of the ME journals in 2010.

Pulsed Eddy-Current Based Giant Magnetoresistive System for the Inspection of Aircraft Structures

Research in nondestructive evaluation is constantly increasing the sensitivity of detection of small cracks embedded deep in layered aircraft structures. Pulsed eddy-current (PEC) techniques using coil probes have shown considerable promise in detection and characterization of buried cracks in multilayered structures. In this paper, we describe the design and development of a nondestructive inspection system that uses pulse excitation of a planar multiline coil to generate a transient field that is detected via a giant magnetoresistive (GMR) field sensor. An analysis algorithm using features in time and frequency domain processes the experimentally measured signals for automatic detection of small cracks under fasteners in multilayered structures at a depth of up to 10 mm.

Frontiers in NDE research nearing maturity for exploitation to ensure structural integrity of pressure retaining components

In this paper, research and developmental efforts that demonstrate high sensitivity detection and characterization of defects and assessment of microstructural degradation, residual stresses and fatigue damage in materials using different non-destructive evaluation (NDE) techniques, have been discussed. Applications of eddy current techniques for quantitative defect characterization and for generalized applications, and remote field eddy current technique for inspection of steam generator and heat exchanger tubes have been discussed. Advanced ultrasonic methods such as time of flight diffraction, synthetic aperture focusing technique, phased array and signal processing for detection, characterization and imaging of defects have been discussed. Applications of ultrasonics and magnetic Barkhausen emission techniques for characterization of microstructures and residual stresses have been discussed. Applications of acoustic emission and infrared thermography techniques for weld quality evaluation of critical nuclear components as part of intelligent processing of materials (IPM) work have been discussed. Application of acoustic emission technique for integrity assessment of pressurized components has been discussed. Development of a software called assets and infrastructure management system (AIMS), for storing and retrieving information for various materials, components and systems, has also been highlighted. The techniques and applications discussed are result of systematic and innovative R&D efforts in the multidisciplinary areas of physics, materials, instrumentation, sensors and softwares for providing solutions to various challenging problems.

Recent Research in Nondestructive Evaluation of Civil Infrastructures

Assessing the condition of a structure is necessary to determine its safety and reliability. Ideally, structural health monitoring should be similar to medical health monitoring of the body. In medical health monitoring, the life signs such as pulse and blood pressure give an overall indication of the overall health of the body. This is analogous to global structural health monitoring, in which damage to the structure can be identified by measuring changes in the global properties of the structure. Once the body signs show an anomaly, we do a battery of tests to determine the cause of the anomaly. Analogously in structural health monitoring, nondestructive evaluation (NDE) can be used to determine the nature of the damage. NDE methods to determine local damage are also becoming more accepted in practice. This paper describes some of the recent and current National Science Foundation projects in this area of research. Promising areas for NDE are identified.

Developments for the non-destructive evaluation of highway bridges in the USA

The collapse of the Silver Bridge in Point Pleasant, West Virginia, in 1967 initiated the formal requirements for the inspection of highway bridges in the USA. Almost 30 years later, visual inspection remains the primary method of bridge inspection. However, many new and promising techniques for the nondestructive evaluation (NDE) of highway bridges have emerged in recent years through the NDE research program of the Federal Highway Administration (FHWA). These include infrared and radar imaging systems, portable ultrasonic systems, telemetry systems, laser deflection measurement systems, and many others. This paper discusses the recent development of these instruments, and the potential impact it may have on bridge inspection and bridge management systems. The paper also discusses the need for validation of system performance, and the FHWA plans to construct a national center for NDE validation at the Turner Fairbank Highway Research Center.

ULTRASONIC NONDESTRUCTIVE EVALUATION APPLIED TO PROSTATE CANCER DETECTION

In this paper we will present initial results from an ongoing project at the University of Missouri-Columbia which focuses on prostate cancer detection using transrectal ultrasound. The overall project goal is the development of effective procedures for the detection, grading, and staging of prostate cancer. The goal of this initial study was lo ascertain whether acoustic parameters used in classical ultrasonic nondestructive evaluation (NDE) of engineering materials may be useful in identifying prostate cancer. The classical parameters speed of sound and attenuation coefficient were used along with a relatively new parameter in ultrasonic NDE, backscatter coefficient. The study was performed in vitro using human prostates which were obtained from radical prostatectomies. Each prostate was transversely sectioned to extract a 2 mm slice which was then scanned in an ultrasonic NDE research laboratory. Cancerous and benign regions of the prostate were subsequently identified on the tissue slice by a pathologist. This scanning and analysis procedure allowed for a one-to-one correlation of actual tissue histopathology and acoustic parameter images. Quantitative data for both tissue types were extracted by using the combination of histopathology images and acouslic parameter images. Results are presented which compare acoustic parameter distributions for cancerous versus benign tissue based on speed of sound, attenuation coefficient, and back-scatter coefficient. The data corroborate the previous in vim result that the acoustic response of cancerous tissue is, on the average, indistinguishable from the acoustic

Applied electromagnetics research and application

Applied electromagnetics researches have been done in the laboratory as one of off-pile research activities. Applied electromagnetics is very important for the design and analysis of magnetic confinement fusion devices and nondestructive evaluation of nuclear fission reactors. Especially, we have developed many numerical analytic methods to solve electromagnetomechanical coupled phenomena in fusion first walls. The numerical results have been validated by the experiments. On the other hand, magnetic nondestructive evaluation plays one of the most important inspections of commercial fission reactor. We are proceeding this magnetic nondestructive evaluation research based on many advanced numerical analysis techniques and the state-of-art sensor technology. Here we describe the analysis of eddy current and magnetic damping of the fusion first wall and several new numerical and experimental techniques in the magnetic nondestructive evaluation for nuclear engineering.
