Promoting Technical Standards Education in Engineering
2016 ASEE Annual Conference & Exposition
The United States Standards Strategy, the framework developed by the American National Standards Institute (ANSI) to guide the U.S. standards system, recognizes the need for standards education programs as a high priority and recommends initiatives that address the significance and value of standards. To this intent, a novel workshop was developed in partnership with the library and the School of Engineering to raise the level of awareness of technical standards and standards usage on campus. The effort was a result of a campus-wide collaboration that provided a low-cost method of introducing technical standards and providing a foundation to develop a series of online tools accessible to the campus community. The event featured guest speakers representative of six major national and international standards bodies in addition to faculty, staff and students. The panels provided discussions on the background of the various types of standards and industries impacted, the development and implementation of these documents, the ways in which students and faculty can become more familiar with these documents and the benefit to becoming actively involved with standards organizations. The presentations and question-and-answer sessions provided a venue to learn about technical standards and to talk about ways to improve standards education within the campus community. The event was well received as shown by strong attendance and follow up to online materials continues to show activity five months following the event. This paper summarizes the implementation of the workshop, its impact, and strategies to further improve standards education on campus.
Fatigue and fracture of wires and cables for biomedical applications
International Materials Reviews
Fine wires and cables play a critical role in the design of medical devices and subsequent treatment of a large array of medical diagnoses. Devices such as guide wires, catheters, pacemakers, stents, staples, functional electrical stimulation systems, eyeglass frames and orthodontic braces can be comprised of wires with diameters ranging from 10s to 100s of micrometres. Reliability is paramount as part of either internal or external treatment modalities. While the incidence of verified fractures in many of these devices is quite low, the criticality of these components requires a strong understanding of the factors controlling the fracture and fatigue behaviour. Additionally, optimisation of the performance and reliability of these devices necessitates characterisation of the fatigue and fracture properties of its constituent wires. A review of cable architecture and stress states experienced during testing is followed by an overview of the effects of changes in material composition, microstructure, processing and test conditions on fracture and fatigue behaviour of wire and cable systems used in biomedical applications.The review concludes with recommendations for future work.
