The measurement method on deformation and strain distribution in a multi-scale range from nanometers to millimeters was investigated by in situ Field Emission Scanning Microscope(FE-SEM) observations. A special loading device was developed and installed into FE-SEM chamber. A multi-scale pattern composed of a grid as well as random and nano-cluster pattern was developed based on electron lithography technique to measure the localized deformation around the interfaces at different scales. The multi-scale measurement method was applied to hierarchical microstructure materials such as hybrid CFRP and Nacre form sea shell to evaluate the mechanical characterization during loading. It is clear that the present study can be used to provide the deformation behaviors at multiple length scales and its related boundary conditions needed for developing a gradient continuum plasticity at different length scales for understanding hierarchical structure materials.

通过原位场发射扫描显微镜（FE-SEM）观测，研究了从纳米到毫米多尺度范围内变形和应变分布的测量方法。开发了一种特殊的加载装置并将其安装到 FE-SEM 室中。基于电子光刻技术，开发了由网格以及随机和纳米团簇图案组成的多尺度图案，以测量不同尺度下界面周围的局部变形。多尺度测量方法适用于混合CFRP和珍珠质贝壳等分层微观结构材料，以评估加载过程中的力学特性。显然，本研究可用于提供多个长度尺度上的变形行为及其相关边界条件，以开发不同长度尺度上的梯度连续塑性，以了解分层结构材料。
