Title Quantitative Inspection Technologies for Aging Military Aircraft.
Publication Date Nov 2013
Media Count 250p
Personal Author D. Barnard J. Bowler L. Brasche L. J. Bond N. Bowler
Abstract Nondestructive evaluation plays a crucial role in the safety of flight, with an increasing importance as military fleet ages and the mission profile is expanded beyond the original design interest. The program completed by the Center for Nondestructive Evaluation at Iowa State University included development of new capabilities to quantify residual stress profiles in Al, Ti, and Ni alloys; expansion of simulation tools for eddy current, ultrasonics, and radiography; advances in probability of detection methodologies including model- assisted POD; improved understanding of emerging methods such as terahertz imaging and vibrothermography; and development of new education materials.
