Paper Title:
Numerical Simulation of Creep-Fatigue Crack Growth for Nickel-Based Super Alloy with Extended Finite Element Method
  Abstract

Extended finite element method is widely used to simulate the discontinuity problems, e.g. fatigue crack growth. This paper mainly analyzes the fatigue crack propagation under elevated temperature in nickel-based super alloy with extended finite element method. Cohesive zone model is used to describe the mechanical behavior around the crack tip. A modified creep damage model is introduced. Fatigue damage and creep damage are accumulated in a linear relationship. And the results produced by computational code are presented and draw a comparison with experimental observation.
