Damage Modeling and Life Prediction

Huge database of material properties (microstructure, thermal-mechanical) and coupon life is available. Proprietary and validated damage models provide very accurate damage accumulation under Creep, LCF, TMF, Creep and Fatigue Crack Growth and their interactions. Life prediction over individual missions or mixes is performed using both deterministic and probabilistic techniques to identify the effect of individual or combined life modes, damage mechanisms as well as relevant uncertainties.

  • Use validated damage models for creep, LCF, thermal and mechanical fatigue, CCG and FCG using material microstructure based constitutive laws
  • Coupon level mechanical test results used for part level life prediction
  • Actual usage based life prediction to identify the fracture critical locations and time to crack nucleation and growth for safe life and damage tolerance assessment
