Experimental Validation For Atomistic Simulations Of The Deformation Of Tantalum

Experimental Validation for Atomistic Simulations of the Deformation of Tantalum

The transition metals exist in several crystal structures due to the influence of the d-bands on bonding. The central transition metals are stabilized in the body-centered-cubic (BCC) structure due to the approximately half filled d-bands. The d-bands have an inherent structure which imparts a directional dependence to the interatomic interactions [1]. These electronic effects, through their influence on the core structure of dislocations, cause the unusual mechanical properties observed in these metals [2]. The purpose of this project was the validation of the predictive abilities of the newly developed MGPT potentials in simulating the defect structures of BCC metals. The validation of these potentials will allow them to be applied with confidence in the simulation of materials behaviors under conditions that are not easily accessible to experimental confirmation.

Applied Nanoindentation in Advanced Materials

Research in the area of nanoindentation has gained significant momentum in recent years, but there are very few books currently available which can educate researchers on the application aspects of this technique in various areas of materials science. Applied Nanoindentation in Advanced Materials addresses this need and is a comprehensive, self-contained reference covering applied aspects of nanoindentation in advanced materials. With contributions from leading researchers in the field, this book is divided into three parts. Part one covers innovations and analysis, and parts two and three examine the application and evaluation of soft and ceramic-like materials respectively. Key features: A one stop solution for scholars and researchers to learn applied aspects of nanoindentation Contains contributions from leading researchers in the field Includes the analysis of key properties that can be studied using the nanoindentation technique Covers recent innovations Includes worked examples Applied Nanoindentation in Advanced Materials is an ideal reference for researchers and practitioners working in the areas of nanotechnology and nanomechanics, and is also a useful source of information for graduate students in mechanical and materials engineering, and chemistry. This book also contains a wealth of information for scientists and engineers interested in mathematical modelling and simulations related to nanoindentation testing and analysis.
