Purpose: This paper analyses the structure and tensile strength of AlSi5Cu2 silumin produced in accordance with PN-EN 1706:2001, categorized as C355 in the US. The study was supplemented with a numerical failure analysis conducted with Abaqus 6.12. Design/methodology/approach: The alloy selected for this study was an Al base alloy containing 5% Si and 2% Cu. Tensile tests on notched round bars with three sizes of the notch radius were performed. Findings: A micromechanical model for the ductility of plastically deforming material was applied to the alloy using the finite-element program ABAQUS. The model is validated by comparing the predictions to experimental results. Research limitations/implications: Average stress triaxiality and ductility for the three types of tensile test specimens were obtained. Originality/value: This paper presented computer simulation of the stress state in notched specimens.
