| Abstract Scope |
Plastic deformation of polycrystalline HCP metals can be severely complex and anisotropic. At the grain scale, several distinct slip families can be active, deformation twinning can occur, while grain boundaries can contribute to the plasticity by sliding and/or migration. The identification and plasticity of these mechanisms is therefore highly challenging and is often achieved only partially by a slip trace analysis, using Digital Image Correlation (DIC) and Electron Backscatter Diffraction (EBSD). Here, we outline a recently introduced framework for Slip Systems based Identification of Plasticity, termed as SSLIP. The SSLIP framework locally matches the measured deformation gradient, obtained by DIC, to the kinematics of the optimal combination of slip system activities. Crystallographic slip from various slip families is robustly and automatically identified for HCP Zn, at each DIC datapoint, while we also propose extensions to the framework to identify and quantify deformation twinning and grain boundary sliding. |
