0242772HallDescription: This award is for support of a joint research project between Dr. Ian Hall, Department of Mechanical Engineering, University of Delaware, Newark, Delaware and Dr. Mustafa Guden, Department of Mechanical Engineering, Izmir Institute of Technology, Izmir, Turkey. They plan to study the propagation of elastic, plastic and shock waves through combinations of solids (engineering, structural or geological materials) through a program consisting of modeling and experiments. The goal is to develop computational tools to facilitate the design of material systems in which the passage of waves can be manipulated to achieve a variety of desired effects. The particular application behind this research concerns wave propagation in materials consisting of ceramic tiles attached to thick-section polymer composites, such as may be used in armors. It has been observed that even when subjected to an initially compressive wave, to which its resistance is good, the ceramic soon experiences a tensile reflected wave to which its resistance is very poor and rapid failure occurs. Interposing a third material, with different properties, between the two principal constituents has been shown to affect the behavior beneficially. The systematic study of the extent to which the behavior may potentially be affected by deliberately choosing the materials' relative dimensions, impedances and other properties is a focus of this research activity. Scope: This award is for a US scientist to collaborate with a Turkish scientist in a research project in an important scientific area. The collaboration will take the form of six-month reciprocal visits by the U.S. principal investigator and his Turkish collaborator. The collaboration will include joint advisement of graduate students, and reciprocal visits by U.S. and Turkish graduate students. This project is jointly funded by the Office of International Science and Engineering and the Division of Civil and Mechanical Systems.

0242772 HALLDESCRIPTION：该奖项是为了支持特拉华大学机械工程系Ian Hall博士，纽瓦克大学，特拉华州的机械工程系和土耳其Izmir Technology Institute的机械工程系Mustafa Guden博士。他们计划通过固体（工程，结构或地质材料）的组合来研究弹性，塑料和冲击波的传播，该程序包括建模和实验。 目的是开发计算工具，以促进可以操纵波浪通过以实现各种期望效果的材料系统的设计。 这项研究背后的特定应用涉及波浪在由厚截面聚合物复合材料附加的陶瓷瓷砖组成的材料中的传播，例如可以在装甲中使用的材料。 已经观察到的是，即使受到最初压缩波（其耐药性良好）的影响，陶瓷很快就会出现拉伸反射波，其抗性非常差，并且会发生快速失败。 在两个主要成分之间插入具有不同特性的第三种材料已被证明会对行为有利影响。 对行为的系统研究可能会因故意选择材料的相对维度，阻抗和其他特性而可能受到影响的程度。 范围：该奖项是为了使美国科学家与土耳其科学家合作，在一个重要的科学领域的研究项目中。 该合作将采用美国首席调查员及其土耳其合作者的六个月相互访问的形式。 该合作将包括对研究生的联合建议，以及美国和土耳其研究生的相互访问。 该项目由国际科学与工程办公室以及民用和机械系统部共同资助。
