Integrated Rotor Crack Model

We present an integrated rotor crack model implemented in MATLAB that serves as a valuable reference for engineers conducting related design work. This comprehensive model employs advanced fracture mechanics algorithms to predict crack propagation behavior in rotors under various operational conditions. The implementation includes key functions for stress intensity factor calculation, fatigue crack growth rate estimation, and life prediction algorithms based on Paris' law or similar damage accumulation models. The model provides designers with essential data and information required for rotor integrity assessment, including crack growth trajectories, remaining life estimates, and critical speed modifications due to crack presence. Utilizing this model enables designers to gain deeper insights into rotor crack behavior, optimize design configurations through parametric studies, and ultimately enhance rotor reliability and safety. The code structure features modular design with separate functions for load processing, material property handling, and crack propagation simulations. Additionally, we offer training sessions and technical guidance to help users better understand the underlying algorithms and effectively apply this model to their specific engineering applications.
