Use of Spherical Nanoindentation to Characterize the Anisotropic Properties of Microscale Constituents and Interfaces in Hierarchically Structured Composite Materials
Year: 2015
Type: report
Abstract: A major impediment to the development of physics-based multi-scale homogenization (composite) theories is the lack of appropriate methods to characterize the local anisotropic elastic-plastic properties of microscale constituents and interfaces at various hierarchical length scales in composite material systems.This work aims to address this gap by combining the information obtained from spherical nanoindentation with different indenter sizes, structure characterization methods (e.g., Orientation Image Mapping in Scanning Electron Microscope, X-ray micro-tomography), and sophisticated finite element models to arrive at reliable estimates of the 1.
