Asymptotically exact theory of fiber-reinforced composite beams
Khanh Chau Le, Tuan Minh Tran
An asymptotic analysis of the energy functional of a fiber-reinforced composite beam with a periodic microstructure in its cross section is performed. From this analysis the asympt…
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…
Thermodynamic dislocation theory: torsion of bars
K. C. Le, Y. Piao, T. M. Tran
The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here in an analysis of a bar subjected to torsion. Employing a small set of physics-base…
Thermodynamic dislocation theory: Bauschinger effect
Khanh Chau Le, Tuan Minh Tran
The thermodynamic dislocation theory developed for non-uniform plastic deformations is used here to simulate the stress-strain curves for crystals subjected to anti-plane shear-con…
Thermodynamic dislocation theory of adiabatic shear banding in steel
Khanh Chau Le, Tuan Minh Tran, James S. Langer
The statistical-thermodynamic dislocation theory developed in our earlier studies is used here in an analysis of the experimental observations of adiabatic shear banding in steel b…
Dislocation mediated plastic flow in aluminum: comparison between theory and experiment
Khanh Chau Le, Tuan Minh Tran
The theory of dislocation mediated plastic flow proposed by Langer, Bouchbinder, and Lookman is applied to compute the stress-strain curve of aluminum and aluminum alloys over a wi…
