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…
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…
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…
Covering a surface with pre-stressed ribbons : from theory to nano-structures fabrication
Alexandre Danescu, Philippe Regreny, Pierre Cremillieu +2
The paper deals with the fabrication of nano-shells from pre-stressed nano-plates release. Due to geometrical and technological restrictions we have to cover a given surface with t…
Design of pre-stressed plate-strips to cover non-developable shells
Alexandre Danescu, Ioan R. Ionescu
In this paper we address the following design problem: what is the shape of a plate and the associated pre-stress that relaxes toward a given three-dimensional shell? As isometric…
Tempering the mechanical response of FCC micro-pillars: an Eulerian plasticity approach
Oguz Umut Salman, Ioan R. Ionescu
The mechanical response of almost pure single-crystal micro-pillars under compression exhibits a highly localized behavior that can endanger the structural stability of a sample. R…
Corners in soft solids behave as defects in crystals
Robin Masurel, Matthieu Roché, Laurent Limat +2
All phases of matter, solid, liquid or gas, present some excess energy, compared to their bulk, at their interfaces with other materials. This excess of energy, known as the surfac…
