| dc.description.abstract | 在新興的奈米科技領域之中，奈米材料的製造方法以及結構已經被廣為研究；想要利用各種奈米材料來做應用，勢必要先了解奈米材料的各種特性，其中又以機械性質為最重要的性質之一。而對於奈米材料機械性質的測定，已經有許多方法被提出，奈米壓痕技術就是近年來最被廣泛應用的一種。
奈米壓痕技術可以測定薄膜材料的模數、硬度等機械性質，近年來更被應用在奈米線的機械性質測定上。但由於奈米壓痕技術在理論上只能被用在測定薄膜材料或塊材的機械性質，所以要利用奈米壓痕技術測定線材的機械性質，勢必會產生誤差。本文就利用有限元素軟體，模擬並分析壓印線材時材料的行為反應，從中找尋誤差的來源並修正。 由於利用奈米壓痕技術測定奈米線材的機械性質日益重要，但舊有的理論方法並無法完全符合需求，故本文的結果將能使奈米線、奈米管等奈米材料的機械性質測定更為正確，也對新式奈米材料的研究做出貢獻。 | zh_TW |
| dc.description.abstract | In the emerging field of nanotechnology, the manufacture method and the structure of nano-materials has been studied widely. The properties of nano-materials are very important to the research of nano-materials. In particular, the mechanical properties are the most important properties in the application of nano-materials. Although many methods of mechanical properties measurement were proposed, nanoindentation test is the most popular method in the recent years.
Nanoindentation test has been extensively applied to measure the elastic modulus and hardness of thin film materials or bulk materials. However, the deviation of predicted contact area could occur when indentation test is applied to wire materials. The reason is that the boundary condition of wire materials is different from bulk materials. In this study, we demonstrate a method to evaluate these errors by using finite element method to analyze the indentation behavior of wire materials and correct the error. Since the mechanical properties measurement of nanowires and nanotubes become more and more important. Previous theory can not completely accord with the demands. The result of this paper makes the measurement method more correct, and also makes the contribution to the study of new nano-materials. | en |
