Nondestructive Testing and Evaluation of Materials at the US Army Research Laboratory

The US Army Research Laboratory (ARL) and its predecessor organizations have been users of and leaders in various methods of nondestructive testing and evaluation (NDT/NDE) throughout much of their collective history. Over the years, the particular set of methods used and the research in them, as well as the Army’s application areas, have changed along with the mission and goals of the organization. In this paper, the authors first give a brief history of ARL and then discuss how the NDT functions are organized into laboratories, laboratory operations, and equipment and capabilities. Major areas of both past and current NDT work and programs are discussed, and a few current “thrust” areas with major emphasis are highlighted. Finally, the overall discussion of the NDT organization and its operations, capabilities, and current work and programs is summarized.
