Steel bars used for pre-stressing concrete and as tensile armour wires are routinely subjected to reverse bending and straightening test to detect laminations in the bars. In this paper, three dimensional FE simulation of the reverse bending and straightening of steel wires over rotating rollers conducted as a part of the research to numerically investigate the effects of the combination of reverse bending and laminations on the tensile properties of bars for civil engineering applications is presented. The appropriateness of the simulation procedure employed in this work is demonstrated by a good agreement between the finite element and experimental results.
