Development of appropriate algorithms for fast and reliable creation of digital representation of dual phase (DP) microstructures is described with the paper. Modified Voronoi tessellation and cellular automata grain growth algorithms are described first to highlight difficulties in realistic description of the DP morphology by artificial numerical approaches. To solve presented limitations a modified Monte Carlo algorithm dedicated to creation of 2D and 3D virtual representations of DP steel is proposed. Details of the developed approach as well as examples of obtained results are presented within the work. Finally obtained 3D digital representation of dual phase steel is subjected to numerical simulation of cold cube compression test to investigate differences occurring in the two phases during plastic deformation.

W opracowaniu przedstawiono wyniki analizy numerycznej procesu zaciskania tulei między innymi na linach stalowych przy pomocy obrotowych segmentów bruzdowych. Omówiono obszary zastosowań wyrobów typu liny i cięgna oraz przedstawiono sposoby wykonywania na nich zakończeń. Analizę numeryczną procesu przeprowadzono w oparciu o metodę elementów skończonych (MES), wykorzystując komercyjny pakiet oprogramowania DEFORM - 3D. Omówiono modele geometryczne zastosowane w obliczeniach oraz wpływ kształtu wykroju na jakość wyrobu. Uzyskane wyniki analizy numerycznej wykorzystano w projekcie przyrządu do praktycznej realizacji tego procesu.
