Abstract

The pull-out problem has frequently been solved in cracking of composite structures. Previously, several numerical studies were carried out using the FEM, [4], and the BEM, [5], and the results were compared with available literature having mainly been focused on experiments. The comparison of both numerical and experimental results were in a good agreement. A remarkable feature of the mathematical solution occurred: a cracking was initiated not only at the face of the fiber-matrix system but also inside the trial body. As the previous formulations accepted the linear behavior of both the fiber and the matrix only, a natural question arises: what happens when the matrix will behave more realistic, i. e. the material of the matrix will obey the von Mises-Huber-Heiicky criterion of plasticity. The answer to this question is the objective of this paper. 1 Introduction
