Abstract
A model based on continuum theory for describing the cyclic deformation behaviour of grey cast iron under multi-axial loading is presented and compared with test results obtained from strain-controlled tension/torsion tests. The unsymmetrical stress-strain response of cast irons under tension and compression is modelled by taking into account the opening and closing of graphite flakes, the bulk stress of cast iron being directly related to the internal stress acting on the steel matrix. Predictions are compared with experimental results obtained from proportional and non-proportional biaxial tests. The method is simple yet able to describe the essential features of the deformation of grey cast iron, and can be easily integrated with existing elasto-plastic constitutive models.
