| Summary: | Glass and ceramics are brittle in nature, but are often used in electronics, space, defense, biomedical and many day-to-day applications, where mechanical disintegration may cause total failure of the particular application. Evaluation and in-depth knowledge of nanomechanical characterization helps to improve process parameters or may help identify the critical failure point. Therefore, it is challenging as well as important to measure mechanical properties such as hardness and Young's modulus at the local microstructural length scale, because any mechanical disintegration starts from the sub-micron scale of the microstructure mainly for brittle materials, including glass, ceramic, ceramic matrix composites and coatings. However, this is not always easy. Processing of ceramics in particular is difficult with "zero" defect. Processing flaws or a characteristically heterogeneous microstructure always hinder the nanomechanical measurements. In general, the scatter in the nanoindentation data is very high for ceramics, coatings and thin films, presumably due to their heterogeneous structure. This book shows how scatter data may be possible to explain with the application of Weibull statistics. It also offers an in-depth discussion of indentation size effect, the evolution of shear induced deformation during indentation and scratches and includes a collection of related research works. |
