The Multi-Scale FEM Simulation of Wire Fracture during Drawing of Perlitic Steel
The fracture development during wire drawing operation is an important phenomenon governing the productivity as well as the mechanical properties of the drawn wire. The wire drawing processes was investigated in present paper in two separate levels - using the 2-dimensional rigid-plastic finite element method (macro-level) and modelling the microstructure changes (micro-level) by the Representative Volume Elements (RVEs). To predict fracture initiation the phenomenological theory of fracture is used. The influence of initial cementite lamellas orientation on triaxity factor and localization of deformation in micro-level is investigated. Obtained results are helpful for a fundamental understanding of pearlitic deformation during development of high strength steel wires for tire cord applications.
