Abstract:
Creep life prediction of a high strength steel plate is important in the context of its application as a blast furnace structural element. Numerical analysis using ANSYS was carried out on a high strength steel plate that was simply supported at its one edge and subjected to an in plane constant tensile stress at the opposite edge. Material parameters were derived from the tensile test data and published literature. Bilinear material model and isotropic hardening along with Bailey–Norton time hardening formulation were employed. Simulated creep tests were performed from ambient temperature to temperatures up to 773 K for varying stresses. At the highest operating temperature, it is safe to load the plate up to 55% of its room temperature yield strength but it can survive only nine and half years at 62% of its room temperature yield strength.
