An interdisciplinary research program in the area of intelligent materials systems and adaptive structures will be developed, with the primary focus being the development of the fundamental science base necessary for the implementation of this technology in U.S. applications. During the initial program period, electrorheological (ER) materials and their usage in applications will be studied. Theoretical efforts in the areas of ER material rheology, ER material pre-yield adaptive structures, and ER material post-yield adaptive devices will be performed. All initial efforts will be extensions of research by the present investigator while the previously employed at Lord Corporation. Further development of a microscopic model of ER material behavior will be completed, and the rheological response of state-of-the-art ER formulations will be simulated. Knowledge of pre-yield behavior will be utilized in a study of ER material adaptive structures, during which a structural response theory will be further developed. Rheological information related to post-yield response will be coupled to the development of an improved theory for ER material controllable device performance. The overall impact of the investigation will be possible, the improvement of the fundamental theoretical understanding of ER materials and their usage in applications.

将开发智能材料系统和自适应结构领域的跨学科研究计划，主要重点是开发在美国应用该技术所需的基础科学基础。 在最初的项目期间，将研究电流变（ER）材料及其在应用中的用途。 将在ER材料流变学、ER材料屈服前自适应结构和ER材料屈服后自适应装置等领域进行理论研究。 所有最初的努力都将是现任调查员先前受雇于洛德公司时的研究延伸。 缓释材料行为微观模型的进一步开发将完成，并且将模拟最先进的缓释配方的流变响应。 预屈服行为的知识将用于 ER 材料自适应结构的研究，在此期间将进一步发展结构响应理论。 与屈服后响应相关的流变信息将与 ER 材料可控器件性能的改进理论的发展相结合。 这项研究的总体影响将是可能的，提高对电流变材料的基本理论理解及其在应用中的使用。
