Simulation Studies Of Nodular Iron’s Bull’s Eye Effect On Stress Concentration Under Plane Stress Conditons

Abstract

A simulation study on the effect of the “bull’s eye” in ductile iron on stress

concentrations was done in this work. Using the model of graphite nodules in a cavity, a

two dimensional plate strip was subjected to plane stress conditions. The results were

compared to the traditional theory of modeling the graphite as holes (cavity) in the iron

matrix. In plane stress conditions, while the graphite in the hole model showed the hole

as areas of stress concentration and therefore very critical as regards fracture, the hole

model showed stress concentrated away from the holes making the holes not very

critical factor as regards fracture. It was observed that areas of stress application were

more critical than the voids when using the hole model. Also the graphite in the hole

model was able to predict the good damping behaviour of ductile iron and the increasing

elongation with decreasing nodule count.
