Full Description
Recent advances in data analysis protocols have transformed indentation from being used merely as a qualitative tool for comparing materials to a rigorous material characterization tool, and a tool for analyzing the stress-strain characteristics of materials. This book collects and presents all of the important details of the key protocols (many of them recently developed) for the convenience of engineers and scientists in the materials manufacturing industry, OEMs, research laboratories, and academic institutions. Kalidindi and Pathak explain the protocols used in generating indentation stress-strain curves and extracting meaningful properties from measured load-displacement data in spherical nanoindentation. They also demystify the use of nanoindentation as a material characterization tool that provides robust quantitative assessment of a material's mechanical properties. Materials covered range from metals to biomaterials.This exploration of nanoindentation includes coverage of: the use of new data analysis protocols to establish estimates of mechanical properties from the initial loading segment in the indentation experiments; the potential of characterizing the samples with indentation in conjunction with other structure quantification techniques in order to establish novel protocols for extracting new information needed to formulate material constitutive laws at the lower length scales; the combined use of orientation imaging microscopy (OIM) and nanoindentation; the combined use of Raman spectroscopy and nanoindentation on bio-samples; and new insights into the buckling response in dense carbon nanotube (CNT) brushes. Datasets are provided for a broad range of materials systems (from metals to biological materials). Fully analyzed examples are included, with details of the analysis steps. Methods and Protocols are provided with enough detail to replicate in the lab. It also includes important tips/guidance on how best to prepare samples for successful measurements.
