Mixed Mode Fracture Mechanics and Crack Growth Analysis in Steam Turbine Discs for Remaining Life Assessment under Thermal Stresses and Mechanical Loading
The long‑term performance and structural integrity of steam‑turbine discs are strongly influenced by crack‑growth behavior under combined thermal stresses and mechanical loading. In this study, a comprehensive analytical framework based on finite element analysis (FEA), mixed‑mode fracture‑mechanics evaluation (Modes I...
