Assessment and validation of SPH modeling for nano-indentation

Abstract Nano-indentation tests are important techniques in material science. Over the past two decades, many numerical approaches have been proposed to model and simulate nano-indentation process. In this paper, possibility of modeling process using a meshless technique, known as smooth particle hydrodynamics (SPH), is explored. particular, SPH conducted ANSYS/LS-DYNA software three different published studies benchmarks. More specifically, results reported by Guo et al. (J Semicond 36:083007, 2015) when nano-indenting KPD crystal were used first verify validity established work. Following this, outcomes further simulations found compare well against finite element experimental Dao (Acta Mater 49:3899–3918, 2001) Karimzadeh (Comput Sci 81:595–600, 2014) for both micro- nano-indentation, respectively. These observations suggest that technique with potential be considered more widely researchers investigating high strain, or strain rate, deformation phenomena on nanoscale. For example, presented research development SPH-based lays foundations toward formulating comprehensive accurate simulation nanoscale tool-based machining processes.
