The Elastic Vibrations, Smart Structures and Their Solution Technologies
The purpose of this NSF-DST supported workshop is to increase multi-author research involving international collaboration that will have the potential of strengthening the U.S. share of science & Engineering (S&E) publications world wide, and thus it will directly translate into U.S. scientific capabilities. Also, the mutual benefits anticipated from the proposed U.S. - India workshop activities are mapped by the following two objectives:
1) Layout a well-developed research plan appropriate for future cooperative research in the areas of elastic vibrations and smart structures (e.g. magnetostrictive particles, embedded in a host materials, act as both sensor and actuators) that has broader impact on space science and other engineering applications; and additionally, identify some advanced research tools (e.g. computer graphic software, numerical solution technologies involving, for example, finite-element method) to solve problems more comprehensively.
2) Establish future cooperative research partnership and make use of unique research environment and resources that the prestigious engineering institution - The University of Roorkee (UoR), India offers to U.S. scientists and engineers for this workshop related activities.
The host institution University of Roorkee (UoR), India, the oldest engineering institute has agreed to support 4-days workshop that will allow 30 participants (10 U.S. and 20 Host Institution) to interact and share their research ideas with fellow scientists and engineers. The UoR is most connected hub of engineering institutions in India. All thirty participants have earned a Ph. D., and are current in their areas of specialization. The U.S. participants have provided their abstracts of presentations, resume and letters of support (see attachments). At present, all participants are actively conducting advanced research, and all U.S. participants come from institutions (listed below) that require from their faculty an active participation in research
University of Utah, Utah
Purdue University, West Lafayette, IN
University of Maryland College Park, MD
Virginia Polytechnic Institute & State University, VA
Coppin State College - University System of MD
U.S. Naval Academy, Annapolis, Maryland
University of Akron, Ohio
The workshop presentations made by the participants will be from the broader area of Mechanics of Solids and Structures (applied mathematics). More specifically, in the workshop presentations, the vibration control problems of engineering structures (e.g., beams and plates) and their shape control and shape design will be emphasized. The new smart materials (such as magnetostrictive composites having remote excitation capability that allow vibration control of space structures) and material damage problems will also be discussed. In these smart structure problems, the effects of large deformations and material-nonlinearity are of great importance. The analysis of non-linearity can give insight into material behavior at or near failure. The digital computing and finite-element method of discretization have allowed solution of some problems of mechanical behavior of intricate material systems. The continuous remeshing and adaptive meshing techniques can be used today for sidestepping the difficulties associated with deformation induced element distortion. Therefore, some portion of the workshop duration will be utilized to identify and plan some advanced and effective solution technologies.
This workshop process will take U.S. researchers few steps closer to achieving the goal of solving complex research problems by: 1) developing the plan to include the problems in vibrations and smart structures that are critical in satellites, space station, electronics circuit boards, and other such scientific and engineering areas where admissible vibration tolerances are small. 2) Identify and layout advanced solution technologies that are effective and comprehensive in finding the solutions. This proposal plan aims at enhancing a productive partnership that allow inter-institutions internationally, and intra-institutions within U.S. to overcome the traditional reluctance to work collaboratively. Lastly, the workshop proceedings will be published for disseminating the research information presented in the workshop, and a workshop report will include: a) The future cooperative research plans emerging from the workshop, b) Evaluation of the workshop implementation as viewed by the participants. The workshop participants will not engage themselves in any future research plan and discussion that relates to nuclear sciences.
