WebSep 7, 2024 · The brittleness/toughness of a material (i.e., its resistance to crack propagation) (), depends on the dislocation activities near the crack tip ().Crack tip plasticity, which slows down or arrests the advancing crack, consists of two distinct processes: nucleation of dislocations at or near the crack tip and their gliding away from the crack … Webdescribing incipient plasticity that combines results of atomistic and finite-element modelling, theoretical concepts of structural stability at finite strain, and experimental analysis. We quantify two key features of the nucleation and subsequent evolution of defects. A position-sensitive criterion based on elastic stability the posse cast

WebJul 1, 2004 · We propose a nucleation theory-based analysis for incipient plasticity during nanoindentation and predict the statistical distribution of rate-dependent pop-in events for … WebIn this paper we focus on incipient plasticity, the very initial stages of plastic activity, in an aluminum thin film subjected to nanoindentation. We investigate the mechanisms whereby dislocations are nucleated, their subsequent interactions, and the effects of indenter geometry and film crystallography. WebThe incipient plasticity indicates the nucleation or activation of defects in materials and enables us to study the intrinsic mechanical properties of materials. In this dissertation, instrumented indentation technique was employed to study the incipient plasticity of metals (bcc-Cr, fcc-Ni, fcc-Au) and a fcc-structured high entropy alloy (HEA) NiFeCoMnCr.
