Abstract

The effect of superimposed hydrostatic pressure on percentage reduction of area (a gauge mark of the ductility) is investigated in round steel bars in tensile stress by employing a finite element analysis (FEA) with 8-node serendipity quadrilateral elements and von Mises plasticity flow rule in an elastoplastic power law hardening model. It is demonstrated that a linear relationship exists between the pressure and percentage reduction of area at any given value of percentage elongation varying from 0.15 to 0.456 with step increase of 0.05. This finding by the finite element analysis is in consonance with the experimental finding by a research work that the plot of the ratio of the area of the tensile part of the break to the total area as a function of pressure is roughly linear and that there is no evidence that the linear relation between pressure and ductility will cease to hold at pressures higher than that were reached in the experiments.

Keywords: Ductility, finite element analysis (FEA), hydrostatic pressure, von Mises plasticity flow rule, elastoplastic, power law hardening
