The elastic stress field arising in the single-fiber pull-out test
TL;DR: In this article, the authors analyzed the stress field arising in the single-fiber pull-out test within the framework of the linear theory of elasticity, and showed that the stress distribution in the vicinity of the fiber is strongly inhomogeneous and exhibits severe concentrations of shear and radia stresses at fiber entry and at the fiber end.
