    window to worldwide NDE advances Attendance at annual QNDE meeting with proceedings Personal contacts with industry leaders from a variety of industrial sectors and associated perspectives Opportunity to network Informal environment NDE engineers from the same industry with common problems NDE engineers from other industries with complementary perspectives solutions CNDE sponsoring companies also have available a partner that secures funding when the opportunity exists to further advance items of particular common interest CNDE has served as a facilitator of government programs a subcontractor to sponsors to provide technical support and partner in jointly funded efforts With CNDE you have a skilled and committed team member to support applications of generic results to specific company problems in proprietary efforts as requested Work can include ITAR EAR compliance when required Nondestructive evaluation plays a critical role in the safety and economics of many of our engineered systems systems for which performance demands are ever increasing As costly systems age the focus turns to life extension and the desire to continue use beyond the original design goal Inspection plays a critical role in detecting the presence of age induced defects or damage Simulation tools such as the ultrasonic eddy current and x ray examples shown in the upper right have the benefit of allowing time efficient parametric studies which allow the NDE engineer to optimize the inspection for the geometry material systems and flaw types of interest for their specific application The fundamental understanding of inspection physics embodied in the simulation tools and applied in innovative measurement approaches are at the heart of CNDE s accomplishments Government Programs Over the past 30 years CNDE has had a number of government funded programs that have expanded our expertise and leverage for the sponsors Brief descriptions are provided here DOE BES 1980 1990 Development of NDE methods for application to DOE energy and weapons programs including multi viewing transducers for ultrasonic reconstruction of flaw size shape and orientation unipolar pulser for enhanced frequency bandwidth and improved flaw reconstruction and novel methods for poling piezoceramic transducers to build special beam profiles Gaussian and Bessel beams directly into the transducer element US Air Force 1980 1993 DARPA and the USAF provided initial funding that lead to what became the CNDE Among the developments were fundamental scattering models which served as the kernel of today s simulation tools in ultrasonics NSF IUCRC 1985 present CNDE was the eleventh IUCRC to be established and one of the four most senior programs still recognized by NSF an honor bestowed on Center s with strong industrial support Members of the program provide guidance on the direction of research and share access to the pre competitive generic research results Membership is highly leveraged through a number of federal and state programs Many corporate sponsors utilize CNDE expertise in proprietary projects receiving a more favorable cost structure than non sponsors Through ongoing participation sponsors also have an opportunity to interact more closely with students resulting in stronger internship and full time employee relationships
