Thermodynamic theory of dislocation/grain boundary interaction
Yinguang Piao, Khanh Chau Le
The thermodynamic theory of dislocation/grain boundary interaction, including dislocation pile-up against, absorption by, and transfer through the grain boundary, is developed for…
Dislocation impediment by the grain boundaries in polycrystals
Yinguang Piao, Khanh Chau Le
Thermodynamic dislocation theory incorporating dislocation impediment by the grain boundaries is developed to analyze the shear test of polycrystals. With a small set of physics ba…
Thermodynamic dislocation theory: Size effect in torsion
Khanh Chau Le, Yinguang Piao
The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here for the analysis of twisted copper wires. With a small set of physical parameters t…
Non-uniform plastic deformations of crystals undergoing anti-plane constrained shear
Khanh Chau Le, Yinguang Piao
The present paper studies non-uniform plastic deformations of crystals undergoing anti-plane constrained shear. The asymptotically exact energy density of crystals containing a mod…
Distribution of dislocations in twisted bars
Khanh Chau Le, Yinguang Piao
An asymptotically exact continuum dislocation theory of single crystal bars under torsion is proposed. The dislocation distribution minimizing energy of the bar with zero torque is…
