Plastic instability mechanisms in bimetallic nanolayered composites
Shijian Zheng,Jun Wang,John S. Carpenter,William M. Mook,Patricia O. Dickerson,Nathan A. Mara,Irene J. Beyerlein +6 more
TL;DR: In this paper, the collaborative role of deformation twinning and dislocation transmission on the onset of strain localization in nanolayered composites was investigated in a transmission electron microscopy investigation.
Journal ArticleDOI
Plastic flow stability of nanotwinned Cu foils
TL;DR: In this article, the authors investigated the plastic flow stability of nanotwinned Cu foils via room temperature rolling and found that they exhibited stable plastic flow without shear localization or fracture, even at thickness reduction of over 50%.
Journal ArticleDOI
The effect of roll and clad sheet geometry on the necking instability during rolling of clad sheet metals
TL;DR: In this paper, it was shown that the rolling strain required to produce internal necking in a clad sheet depends both on the volume fraction of each constituent in the clad and the geometry of the rolls.
Journal ArticleDOI
A Simple Model for the Compressive Failure of Weakly Bonded, Fiber-Reinforced Composites:
TL;DR: In this paper, a model for the compressive failure of fiber-reinforced composites with brittle, weakly bonded constituents is presented, where slippage occurs at the fiber-matrix interface when the interfacial shear stress reaches some critical value.

Boudinage as a material instability of elasto-visco-plastic rocks
Max Peters,Manolis Veveakis,Thomas Poulet,Thomas Poulet,Ali Karrech,Marco Herwegh,Klaus Regenauer-Lieb +6 more
TL;DR: In this paper, a random distribution of grain sizes over two orders of magnitude in a central layer embedded in a matrix with a diffusion creep rheology is introduced, which is used to verify the robustness of the numerical solution by first identifying the natural mode shapes and frequencies of the simulated structure and material parameters, including geometric imperfections.
