Effect of creep-fatigue loading condition on crack tip fields of grade 91 steel at crack initiation and growth
Article
Full-text available
  • Sep 2021
In this paper, the effect of creep-fatigue loading condition on crack tip deformation and stress fields of Grade 91 steel at 600 °C at crack initiation and growth is studied. By using finite element debond analysis method, creep-fatigue crack growth tests using C(T) specimens under various load ratios and hold times are simulated, and the effect of...

Linear Elastic Fracture Mechanics Assessment of a Gas Turbine Vane
Article
Full-text available
  • Jul 2022
This work assesses the crack propagation at the most critical point of a second stage of a gas turbine blade by means of linear elastic fracture mechanics (LEFM). The most critical zone where the crack may nucleate, due to a combination of thermo-mechanical loads, is detected with an uncracked finite element (FE) model pre-analysis. Then the sub-mo...

... The node release technique is the simplest approach to simulating the manner of creep crack growth when combined with other damage accumulation theories. For example, a strain-based damage model was proposed in which total damage was assumed to be the linear summation of creep damage, 5 while a node release method on the basis of the NSW ductility exhaustion damage model assists in modeling virtual cracking. 6 A coupled creep damage model to predict creep crack growth can be developed when the accumulated damage has reached a critical value and the elastic modulus of damaged elements drops to a very small value. ...
