Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
This paper mainly studies the creep characteristic of nickel-base superalloy GH4169 under high temperature. From the perspective of modeling methods, based on the continuum damage mechanics, a creep life prediction model was proposed to predict the creep life of metal materials in both uniaxial stress state and multiaxial stress state, and experimental verification is done. Moreover, from the perspective of numerical analysis, it compares the test data with the analysis results obtained by the finite element analysis using Graham creep model, and the comparison result shows that numerical analysis results agree well with the experimental data.
