Center for Nondestructive Evaluation (CNDE) Iowa State University A National Science Foundation Industry/University Cooperative Research Center since 1985 Advances in nondestructive evaluation can enhance the quality and reliability of manufactured products; these same noninvasive measurement techniques are beginning to find application in biological systems Center Mission and RationaleNondestructive evaluation is the use of measurement techniques to non-invasively determine the integrity of a material component or structure. The Center for Nondestructive Evaluation (CNDE) uses quantitative approaches to develop nondestructive evaluation as an engineering tool applicable throughout the life cycle of a structural component. The Center's traditional emphasis has been in the fields of aviation, transportation, energy, and manufacturing, with a mission of conducting directed research that advances the science of nondestructive evaluation and ensures the integrity of structures and materials. These same techniques are now being extended to the development of solutions to agricultural, biomedical, and food processing problems. Research ProgramCNDE conducts a full spectrum of research ranging from the development of measurement models, which describe the fundamental interaction between probing methods and the flaws and properties of materials, to the development of one-of-a-kind prototype instruments. Areas in which the Center is currently conducting research include --
Because the field of nondestructive evaluation requires a multidisciplinary approach, contributions from various engineering disciplines and physical and life sciences are essential. Faculty and scientific staff from 4 colleges and 15 departments have contributed to the research efforts at Iowa State University (ISU). The Center's researchers currently include more than 35 faculty members and full time research staff, as well as some 35 graduate and postdoctoral students and 15 undergraduate students. In addition to participating in the Industry/University Cooperative Research Centers Program, CNDE is active in other major research programs --
Special Center ActivitiesSome of the Center's research, technology transfer, and education/training accomplishments include --
Many companies have used advances developed by CNDE in their manufacturing and service businesses. FacilitiesMost of CNDE's facilities are housed in ISU's Applied Sciences Complex. CNDE research equipment and instrumentation include a comprehensive set of X-ray sources and detectors, high- and low-frequency ultrasonic instruments, ultrasonic phased array equipment, cw and pulsed eddy current instrumentation, photoinductive equipment for characterizing eddy current probes, special purpose equipment for making a variety of magnetic-based NDE measurements in the laboratory and field, a unique "testbed" for validation of models and work related to the role of NDE and materials in concurrent engineering and life cycle management, and a PC-based cluster for performing parallel computations on large-scale problems. In addition, examples of all of the major equipment items used by industry in practical inspections are available.
