CRACK PROPAGATION PREDICTION IN HETEROGENEOUS MICROSTRUCTURE OF NODULAR CAST IRON

The crack propagation prediction occurring on the microstructural level of heterogeneous materials, such as nodular cast iron, is a very challenging problem. According to the results of recent investigations, the emerging phase-field approach to fracture has a strong potential in modelling the complex crack behaviour in a simple manner. In this study, recently developed phase-field staggered solution scheme with the residual norm stopping criterion has been employed for the fracture analysis of heterogeneous microstructure exhibiting complex crack phenomena. The microstructural geometries based on the metallographic images of the nodular cast iron and the material properties of an academic brittle material have been used in numerical simulations where the graphite nodules have been considered as porosities. The proposed algorithm efficiently recovers the complicated crack path driven by the complex microstructural topology.
