Crack nucleation at forging flaws studied by non-local peridynamics simulations Open
We present a computational study and framework that allows us to study and understand the crack nucleation process from forging flaws. Forging flaws may be present in large steel rotor components commonly used for rotating power generation…

Study on fatigue crack initiation and propagation from forging defects Open
In this study, crack initiation and propagation under cyclic loading are first experimentally studied by testing specimens fabricated from a rotor material containing manufacturing defects. The latter represent clusters of non-metallic inc…
