Prediction of ideal orientations in velocity gradient-driven processes for large plastic deformations of crystals
Jalal Smiri, Oguz Umut Salman, Ioan R. Ionescu
We focus on the crystal lattice ideal orientations, also referred to as preferred or attractor orientations, in crystalline materials, and how they can be used to predict the final…
Dislocation saturation in slip rate driven processes and initial microstructure effects for large plastic deformation of crystals
Jalal Smiri, Oguz Umut Salman, Ioan R. Ionescu
Dislocation-density-based crystal plasticity (CP) models are introduced to account for the microstructural changes throughout the deformation process, enabling more quantitative pr…
Large plastic deformation of voids in crystals
Jalal Smiri, Joseph Paux, Oguz Umut Salman +1
The mechanisms of void growth and coalescence are key contributors to the ductile failure of crystalline materials. At the grain scale, single crystal plastic anisotropy induces la…
Accounting for localized deformation: a simple computation of true stress in micropillar compression experiments
Jalal Smiri, Oguz Umut Salman, Matteo Ghidelli +1
Compression experiments are widely used to study the mechanical properties of materials at micro- and nanoscale. However, the conventional engineering stress measurement method use…
