Whilst superseded by other materials, there are many instances of engineering structures in use today that are formed of grey cast iron. These aging assets need to be assessed for their abilities to continue to function, and to predict performance in the event of engineering works being carried out on the asset, or nearby. Grey cast iron does not exhibit an obvious elastic regime when loaded in tension and is often classified in terms of minimum guaranteed tensile strength. Grey cast irons typically fail in brittle cleavage with a strain limit of <1%, therefore an elastic based assessment is often applied despite the hardening properties exhibited. Tensile properties were extracted from dataset, compared to elastic assumption of different and same tension-compressive modulus using a plate model with distributed pressure. Different boundary conditions were applied to simulate potential constraint on a sewer penstock. It was found that the elastic models gave good estimation of the dataset models at lower stress levels, higher on higher stress levels, where increasing hardening is experience.
