The indentation size effect (ISE) of three types of single crystals, i.e. f.c.c. copper single crystal, b.c.c. ß phase of Ti-6Al-4V (ß-Ti-64) and b.c.c. ß phase of Ti-15V-3Cr-3Al-3Sn (ß-Ti-15-3-3-3), is investigated using finite-element analysis. In indentation modelling, an idealised conical indenter and spherical indenters were chosen to study the effects of indenter's geometry on the mechanical response of the tested material. A crystal plasticity model was used to describe the material's behaviour of these single crystals during nanoindentation. In this chapter, a conventional single-crystal plasticity (SCP) model and the mechanism-based strain-gradient crystal-plasticity (MSGCP) model were employed to compare and contrast the (de)merits of the types of crystal plasticity models. © 2017 John Wiley & Sons Ltd.eninfo:eu-repo/semantics/closedAccessCrystal Plasticity ModellingIndentation ModellingIndentation SimulationsIndentation Size EffectMsgcp ModelSingle-Crystal Plasticity ModelBook Part56157710.1002/9781119084501.ch232-s2.0-86000700728WOS:000424147500024N/AN/A
