Safe equilibrium and crack growth in inhomogeneous materials as a variational problem
Khanh Chau Le, Mohammed El Yaagoubi
The variational principle of safe equilibrium for inhomogeneous elastic cracked bodies is formulated. Using the standard calculus of variations, we show that the crack remains in s…
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: Application to bcc-crystals
Khanh Chau Le, Sa Ly Dang, Hoang Thien Luu +1
This paper presents the thermodynamic dislocation theory containing several modifications over its first version which was originally proposed by Langer, Bouchbinder, and Lookman (…
Two universal laws for plastic flows and the consistent thermodynamic dislocation theory
Khanh Chau Le
This paper verifies two laws for plastic flows of face-centered cubic crystals that deform at constant strain rates and fixed ambient temperatures. The first law relates steady-sta…
Scaling Confirmation of the Thermodynamic Dislocation Theory
J. S. Langer, K. C. Le
We show that the thermodynamic dislocation theory (TDT) predicts a scaling relation between stresses, strain rates, and temperatures for steady-state deformations of crystalline so…
Thermodynamic dislocation theory for polycrystals under tension/compression
Tuan Minh Tran, Khanh Chau Le, Thi Hoa Le
Starting from the assumption that all possible orientations of grains are equally probable, we prove that the geometric factor of thermodynamic dislocation theory for polycrystals…
