Book Description
The Materials Research Science and Engineering Centers (MRSEC) Impact Assessment Committee was convened by the National Research Council in response to an informal request from the National Science Foundation. Charged to examine the impact of the MRSEC program and to provide guidance for the future, the committee included experts from across materials research as well as several from outside the field. The committee developed a general methodology to examine the MRSEC centers and after extensive research and analysis, came to the following conclusions. MRSEC center awards continue to be in great demand. The intense competition within the community for them indicates a strong perceived value. Using more quantitative measures, the committee examined the performance and impact of MRSEC activities over the past decade in the areas of research, facilities, education and outreach, and industrial collaboration and technology transfer. The MRSEC program has had important impacts of the same high standard of quality as those of other multi-investigator or individual-investigator programs. Although the committee was largely unable to attribute observed impacts uniquely to the MRSEC program, MRSECs generally mobilize efforts that would not have occurred otherwise. Because of an observed decline in the effectiveness of the centers, the committee recommended a restructuring the MRSEC program to allow more efficient use and leveraging of resources. The new program should fully invest in centers of excellence as well as in stand-alone teams of researchers to allow tighter focus on key strengths of the program. In its report, the committee outlines one potential vision for how this might be accomplished in a revenue-neutral fashion.

Long Term Durability of Structural Materials
Author: P.J.M. Monteiro
Publisher: Elsevier
ISBN: 0080535593
Category : Technology & Engineering
Languages : en
Pages : 313
Book Description
"Long Term Durability of Structural Materials" features proceedings of the workshop held at Berkeley, CA in October, 2000. It brought together engineers and scientists, who have received grants from the initiative NSF 98-42, to share their results on the study of long-term durability of materials and structures. The major objective was to develop new methods for accelerated short-term laboratory or in-situ tests which allow accurate, reliable, predictions of the long-term performance of materials, machines and structures. To achieve this goal it was important to understand the fundamental nature of the deterioration and damage processes in materials and to develop innovative ways to model the behavior of these processes as they affect the life and long-term performance of components, machines and structures. The researchers discussed their approach to include size effects in scaling up from laboratory specimens to actual structures. Accelerated testing and durability modeling techniques developed were validated by comparing their results with performance under actual operating conditions. The main mechanism of the deterioration discussed included environmental effects and/or exposure to loads, speeds and other operating conditions that are not fully anticipated in the original design. A broad range of deterioration damage, such as fatigue, overload, ultraviolet damage, corrosion, and wear was presented. A broad range of materials of interest was also discussed, including the full spectrum of construction materials, metals, ceramics, polymers, composites, and coatings. Emphasis was placed on scale-dependence and history of fabrication on resulting mechanical behavior of materials.
