## Identification and stability of small-sized dislocations using a direct algorithm.(English)Zbl 1481.35388

Summary: This paper considers the problem of identifying dislocation lines of curvilinear form in three-dimensional materials from boundary measurements, when the areas surrounded by the dislocation lines are assumed to be small-sized. The objective of this inverse problem is to reconstruct the number, the initial position and certain characteristics of these dislocations and establish, using certain test functions, a Hölder stability of the centers. This paper can be considered as a generalization of [A. El Badia and A. El Hajj, SIAM J. Appl. Math. 73, No. 1, 84–103 (2013; Zbl 1267.35252)], where instead of reconstructing point-wise dislocations, as done in the latter paper, our aim is to recover the parameters of line dislocations by employing a direct algebraic algorithm.
