Dislocation pattern formation in finite deformation crystal plasticity
Rajat Arora, Amit Acharya
Stressed dislocation pattern formation in crystal plasticity at finite deformation is demonstrated for the first time. Size effects are also demonstrated within the same mathematic…
On the Structure of Linear Dislocation Field Theory
Amit Acharya, Robin J. Knops, Jeyabal Sivaloganathan
Uniqueness of solutions in the linear theory of non-singular dislocations, studied as a special case of plasticity theory, is examined. The status of the classical, singular Volter…
On Weingarten-Volterra defects
Amit Acharya
The kinematic theory of Weingarten-Volterra line defects is revisited, both at small and finite deformations. Existing results are clarified and corrected as needed, and new result…
Stress of a spatially uniform dislocation density field
Amit Acharya
It can be shown that the stress produced by a spatially uniform dislocation density field in a body comprising a linear elastic material under no loads vanishes. We prove that the…
A design principle for actuation of nematic glass sheets
Amit Acharya
A continuum mechanical framework is developed for determining a) the class of stress-free deformed shapes and corresponding director distributions on the undeformed configuration o…
