1. Introduction

1. Introduction

The importance of crack paths in fracture and structural integrity issues is out of doubt. In this conceptual frame, anisotropic materials such as cold drawn pearlitic steels suffer crack deflection and mixed mode propagation as a consequence of the microstructural anisotropy generated by cold drawing.
