Abstract

Abstract

According to the experimental results of dynamic properties of typical aero-engine casing material GH4133B at different temperatures (298～1 073K) and strain rates (10^-1～5×10³s^-1), and in view of intrinsic defects of the J-C model used in the analysis of casing acceptance in engineering applications, a more accurate revised J-C model was proposed to describe the mechanical behavior of GH4133B superalloy. In the meantime, an empirical failure model based on the J-C model was obtained based on test results of material stress triaxiality. Comparison between the model predictions and the experimental results shows that, the established constitutive model and the failure model well predict the plastic flow stress and the failure behavior of GH4133B.
