“…A number of ultrasonic simulators that have been developed including: 1) Champ-Sons [16,17], that is part of a larger simulation package, CIVA, developed by CEA in France, 2) UTDefect, SUNDT, and SIMSUNDT [18], which have been developed at Chalmers University in Sweden, 3) UTSIM, from the Center for NDE, Iowa State University in the USA [19], 4) the Generalized Point Source Synthesis (GPSS) software from IZFP in Germany [20], and 5) the EFIT software developed at the University of Kassel, Germany [21]. These simulators, which have all been used to solve a variety of complex industrial inspection problems, are based on Auld's relationship or the Thompson-Gray measurement model, which shows the influence that those fundamental developments have had on the ultrasonic NDE modeling field.…”

Over the past two and a half decades there has been considerable progress made in the modeling of ultrasonic nondestructive evaluation (NDE) inspections. These models have also been combined with models of the noise and variability present in an inspection to estimate probability of detection (POD) versus flaw size curves. An overview will be given of the past and present accomplishments made in ultrasonic NDE modeling, POD modeling, and the relationship of those advances to reliability modeling that incorporates explicitly the results of inspections. A brief look into the future of this modeling technology will also be given.

Nondestructive testing (NDT) for flaws in materials and structures has undergone an evolutionary change over the past 50 years. In the U.S. it has moved from a testing strategy (NDT) with a zero defects requirement to a test and evaluate technology (NDE) based upon damage tolerant design considerations. Here it is assumed that the part will always contain defects but those greater than a critical size, specified by fracture mechanics, will be removed by inspection thereby resetting the part's service clock. In this talk, events will be identified that were critical in promoting this paradigm shift and in moving on to quantitative NDE (QNDE). A number of major research programs were also initiated to upgrade NDT to meet the new requirements; principal attention in this talk will be given to research highlights initiated in the first of these programs, the DARPA∕AFML Interdisciplinary Program for Quantitative Flaw Definition that was established 35 years ago. Its purpose was threefold: to develop a new core science∕people base for inspection technology that could meet the new requirements, to set the stage for new field-adaptable engineering tools, and to initiate the current continuing series of quantitative NDE (QNDE) meetings. Advances initiated in this program and pursued by many over the years have resulted in a scientific core structure for quantitative NDE (QNDE) based on a linkage of fundamental models of the various measurement processes that are involved in any inspection and∕or technology. These models and their linkage will be discussed and the core structure defined. A new and powerful set of engineering tools-i.e. simulation programs for UT, X-ray, and EC technologies -has also been developed using these models. Applications of these tools will be highlighted and their role in other advanced programs including Structural Health Monitoring and Condition-Based Maintenance will be noted. Finally, a discussion of visions of future opportunities and directions for QNDE will be given. Published by the American Institute of Physics.
