Theoretical modelling of ultrasonic Non-Destructive Testing
Materials & Design, 1994Co-Authors: A. BostrÖmAbstract:The benefits of theoretical modelling of ultrasonic Non-Destructive Testing is discussed and some examples from a recently developed model are given. This includes level plots of the field radiated by a piezoelectric probe and also some examples of signal responses from Testing for cracks.

Thermal Non-Destructive Testing and evaluation of solids
2017Co-Authors: Ravibabu Mulaveesala, Vanita AroraAbstract:This book presents recent advances in thermal/infrared Non-Destructive Testing and evaluation of solid materials by pulse compression favorable non-periodic thermal excitation schemes. It puts together concise and complete information on pulse compression favorable thermal Non-Destructive Testing and evaluation (TNDT&E) methods for industrial inspection of wide verity of materials. This book will help practicing engineers from various disciplines to implement nondestructive evaluation methods on the production line and enhance their knowledge of industrial inspection techniques. It can also be used as a teaching aid at universities especially involved in Testing and evaluation of materials. Finally research centres will find it valuable as a reference book for TNDT&E.

Thermal Non-Destructive Testing and Evaluation: Coming of Age
Journal of Information Technology & Software Engineering, 2013Co-Authors: Ravibabu MulaveesalaAbstract:As a specialized tool for Non-Destructive Testing & Evaluation (NDT&E), Infrared Thermography (IRT) [1-10] involves as a remote mapping of temperature over test sample for finding out its surface and subsurface features with the emitted radiation from objects in the infrared band of the electromagnetic spectrum. It is a fast, remote, and safe Non-Destructive Testing and evaluation (NDT&E) method for surface and sub-surface defect detection in various solid materials. Since most solids conduct heat, IRT largely owes its emergence and potentiality for defect detection in variety of materials such as metals [5], composites [6,7,11] and semiconductors [8,12]. IRNDT has numerous applications in the area of aeronautics, space, electrical, electronic, bio-medical and mechanical industries [5-27]. Of the various possibilities of thermal NDT implementations Infrared Thermography (IRT) or Infrared Non-Destructive Testing (IRNDT) has, gained wide acceptance in NDT & E methods due to its merits. Various methods and techniques have further been developed by various research groups all over the world to improve and widen the use of IRT for Non-Destructive characterization [1,7,10,11,14,15,16,21,23,26]. This editorial is to present an overview on existing work and to describe the most relevant experiences devoted to the use of IRT methods for NDT&E.

quadratic frequency modulated thermal wave imaging for non destructive Testing
Progress in Electromagnetics Research M, 2012Co-Authors: Ghali Venkata Subbarao, Ravibabu MulaveesalaAbstract:Thermal Non-Destructive Testing and evaluation of glass flbre reinforced plastic materials has gained more importance in aerospace industry due to low weight and high strength capabilities in severe environmental conditions. More recently, pulse compression favorable non-stationary excitation schemes have been exhibiting reliable defect detection capabilities in infrared Non-Destructive Testing. This paper introduces a novel infrared Non-Destructive Testing method based on quadratic frequency modulated thermal wave imaging with pulse compression for characterization of glass flbre reinforced plastic materials. Defect detection capability of the proposed method has been experimentally validated using a glass flber reinforced plastic (GFRP) sample with embedded Te∞on inserts. Experimental results proved the enhanced depth resolution capability of the proposed excitation method as compared to the linear frequency modulation with pulse compression.

rapid thermal non destructive Testing of aircraft components
Composites Part B-engineering, 2000Co-Authors: Declan G. Bates, Dawei Lu, G. F. Smith, J HewittAbstract:This paper compares the use of different thermal Non-Destructive Testing techniques to rapidly inspect carbon fibre composite aircraft components. Samples were prepared to simulate inclusions and barely visible impact damage in carbon fibre reinforced plastic laminate which represent faults in the manufacturing process and in-service environment respectively. The limits of material fault detection were then compared for transient and lock-in thermography and the results were verified with underwater ultrasonic c-scans. The paper concludes that lock-in thermography is a more powerful technique to detect impact damage and that transient thermography is more suitable for detecting inclusions. Thermal Non-Destructive Testing is up to 30 times quicker than underwater ultrasonic c-scanning and may ultimately provide the solution to the problem of rapid quantitative in-service and manufacturing process inspection of commercial aircraft components.
