摘要：We study the interaction of a screw dislocation with a multicoated circular inclusion. For given geometric parameters of an N-phase circular inclusion, in which a circular inclusion is bonded to the surrounding matrix through N-2 coaxial coatings, we can properly design the N-1 mismatch parameters of the composite so that there exist N-2 equilibrium positions for the screw dislocation. The designed multicoated inclusion can be considered as a near-cloaking structure for the screw dislocation at these equilibrium positions. (C) 2012 Elsevier Ltd. All rights reserved.
