| Research Abstract |
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.
