Presidential Young Investigators Award: Computational Micromechanics of Solids

首席调查员将使用美国国家科学基金会总统青年调查员奖的资金，对当前研究感兴趣的三个领域进行研究。这些领域可以列在“固体的计算微观力学”下，特别强调新型陶瓷、光学和电子材料。第一个主题是研究陶瓷材料中的相变增韧作为显著提高脆性固体断裂韧性的机制。第二个主题是研究用于光学和电子应用的薄膜的机械性能，第三个主题是用于电子应用的成形晶体熔体生长过程中缺陷的产生。上面列出的三个领域包括相当大的计算组件。计算技术将用于将微观结构变量与宏观和控制参数相关联。

There are three areas of current research interest towards which the principle investigator will use the funds from the NSF Presidential Young Investigator Award. These areas can be listed under "computational micromechanics of solids" with special emphasis on novel ceramic, optical and electronic materials. The first topic is the study of transformation toughening in ceramic materials as a mechanism for considerably increasing the fracture toughness of brittle solids. The second topic is the study of the mechanical properties of thin films for optical and electronic applications, and the third topic is the generation of defects during the crystal growth from the melt of shaped crystals for electronic applications such as gallium arsenide. The three areas listed above include a considerable computational component. The computational techniques will be used to correlate microstructural variables to macroscopic and control parameters.
