Through the looking glass: The future for NDE?

Nondestructive testing (NDT) is a mature industry, with global equipment sales fast moving towards $2B. per year. The use of conventional NDT will grow in developing countries and in developed countries the challenges will include those associated with maintaining aging infrastructure. For some systems the future will move to structural health monitoring (SHM) and for others into integration of online measurements in manufacturing. Nondestructive Evaluation (NDE) is a multi-disciplinary area of endeavor that has its origins in materials science and NDT. It seeks to provide an adequate science base for NDT to become a quantitative science. It was seen to be necessary to better detect, size and type defects, improve the reliability of inspection, and probability of detection (POD). There is particular interest in estimating the potential defects could have on performance or potential for loss of structural integrity, under various loading or stressor conditions, and ultimately implement risk-based reliabili...
