Inelastic finite element analysis of circumferentially notched specimen by damage-coupled inelastic constitutive equation of P91 steel

P91 steel, known for its excellent creep strength and corrosion resistance, is used in key high-temperature equipment in power plants. This equipment has geometric discontinuities such as notches, where cracks will develop due to creep-fatigue loading by subjecting the equipment to start-up, continu...
