GOALI: Fundamental Nonlinear Investigations of Dynamic Nanoindentation

在纳米尺度上探索材料行为的能力对未来的小型化研究（即微纳米器件的设计和制造）至关重要。事实上，连接许多重要应用领域的共同主线是需要在纳米尺度上定量表征材料的行为（例如用于工程应用的多层膜，工程生物材料和细胞膜力学研究）。提出的研究目的是研究固有的测量非线性，往往导致研究人员对动态纳米压痕测试结果的误解。广义地说，建议的努力检查一些最普遍的问题，这些问题混淆了当前的测量数据，以提供非线性校正，这将极大地改善报告的测量结果。

The ability to explore the material behavior on the nanoscale is of primary importance to future miniaturization research (i.e. the design and fabrication of micro- and nano-scale devices). In fact, a common thread linking many important application areas is the need to quantitatively characterize material behavior on the nanoscale (e.g. multi-layer films for engineering applications, engineered biomaterials, and studies of cell membrane mechanics). The objective of the proposed research is to study inherent measurement nonlinearities that often cause research scientist to misinterpret the results of dynamic nanoindentation tests. Broadly speaking, the proposed efforts examine some of the most prevalent problems that confound current measurement data in an effort to provide nonlinear corrections that will greatly improve the reported measurement results.
