Strain Gradient Crystal Plasticity Approach to Modelling Micro-Plastic Flow and Localisation in Polycrystalline Materials Simonovski, Igor; Yalçınkaya, Tuncay (2015-09-17) Structural materials in the reactor pressure vessels are exposed to a harsh environment, resulting in a number of material degradation processes. Irradiation generates a number of point defects in the atomic structure of a material. In addition, plastic slip localization occurs on the grain level size where highly-deformed narrow bands of material appear already at the moderate strain levels. These bands are called channels or clear bands, because they are almost empty of irradiation defects, whereas the su...
Strain-induced alignment and phase behavior of blue phase liquid crystals confined to thin films Büküşoğlu, Emre; Wang, Xiaoguang; Zhou, Ye; de Pablo, Juan Jose; Abbott, Nicholas L (2017-12-21) We report on the influence of surface confinement on the phase behavior and strain-induced alignment of thin films of blue phase liquid crystals (BPs). Confining surfaces comprised of bare glass, dimethyloctadecyl [3-(trimethoxysilyl)propyl] ammonium chloride (DMOAP)-functionalized glass, or polyvinyl alcohol (PVA)-coated glass were used with or without mechanically rubbing to influence the azimuthal anchoring of the BPs. These experiments reveal that confinement can change the phase behavior of the BP film...
Strain gradient crystal plasticity: Intergranular microstructure formation Özdemir, İzzet; Yalçınkaya, Tuncay (Springer International Publishing, 2016-01-01) This chapter addresses the formation and evolution of inhomogeneous plastic deformation field between grains in polycrystalline metals by focusing on continuum scale modeling of dislocation-grain boundary interactions within a strain gradient crystal plasticity (SGCP) framework. Thermodynamically consistent extension of a particular strain gradient plasticity model, addressed previously (see also, e.g., Yalcinkaya et al, J Mech Phys Solids 59:1-17, 2011), is presented which incorporates the effect of grain ...
