TL;DR: In this article, an analysis of Vickers and Berkovich indentation experiments through extensive crystal plasticity finite element simulations is performed by recourse to the Bassani and Wu hardening model for pure fcc crystals undergoing both easy-glide stage I and stage II deformations, as well as with the model proposed by Pierce, Asaro and Needleman for precipitation hardened fcc crystal, deforming initially under stage II which also undergo strong hardening saturation in stage III.

TL;DR: In this article, the authors examined the phenomenon of flexoelectric switching of polarization in ultrathin films of barium titanate induced by a tip of an atomic force microscope (AFM).

TL;DR: In this paper, the optical transmittance, band gap, and refractive indices of the ZnO:Ni thin films with different Ni concentrations were deposited on Si (1/0/0) and corning glass substrates at 400°C by reactive magnetron sputtering using Ar and O 2 gas mixture.

TL;DR: In this article, a visco-plastic self-consistent model is compared with a crystal plasticity finite element model to predict grain curling in tungsten wires.

TL;DR: In this article, the authors show that material bulging against the indenter-tip is a distinctive feature in nanocontact plasticity associated with intermittent defect bursts, which is enhanced by recurrent slip traces introduced throughout the contact surface, as in the case of strongly linear defect networks in FCC Al, and by specific twin arrangements at the vicinity of BCC nanoimprints.
