Averaging in thermodynamic dislocation theory: general macroscopically uniform stress and strain states
Khanh Chau Le
The averaging procedure, developed for polycrystalline bars under axially symmetric tension or compression, is extended to arbitrary macroscopically uniform stress and strain state…
Formation of grain boundaries in ductile single crystals under plane-strain simple shear: a block-coordinate finite element method
Khanh Chau Le, Thanh Danh Nguyen
Large plastic deformation can drive an initially uniform single crystal to spontaneously subdivide into misoriented grains separated by thin dislocation walls -- a pattern-forming…
A phase field model of coupled crack and dislocations: emission, blunting, and the necessity of dissipative toughening
Khanh Chau Le, Thi My Kieu Tran
We propose a phase field model of a macrocracked single crystal in which the crack and the geometrically necessary dislocations descend from a single energy functional. Energy mini…
An asymptotically exact first-order shear deformation theory for functionally graded plates
Khanh Chau Le
An asymptotically exact first-order shear deformation theory for functionally graded elastic plates is derived using the variational-asymptotic method. As an application, an analyt…
Theory of transition from brittle to ductile fracture
Khanh Chau Le, Hyeonyeong Jeong, Tuan Minh Tran
In this paper, two improvements to the theory of transition from brittle to ductile fracture developed by Langer are proposed. First, considering the drastic temperature rise near…
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…
