Abstract

In an interesting recent paper [1] (A. Acharya, Stress of a spatially uniform dislocation density field, J. Elasticity 137 (2019), 151--155), Acharya proved that the stress produced by a spatially uniform dislocation density field in a body comprising a nonlinear elastic material may fail to vanish under no loads. The class of counterexamples constructed in [1] is essentially 22-dimensional: it works with the subgroup O(2)IdO(3)\mathcal{O}(2) \oplus \langle{\bf Id}\rangle \subset \mathcal{O}(3). The objective of this note is to extend Acharya's result in [1] to O(3)\mathcal{O}(3), subject to an additional structural assumption and less regularity requirements.
