MICRO-MECHANICAL MODEL OF A SINGLE CRYSTAL NICKEL-BASED SUPERALLOY

摘要

A multi-scale micro-mechanical model for a nickel-base superalloy is presented. The model takes into account the multiphase character of the material and is thus able to predict the effect of microstructure morphology on the macroscopic material response. The model is implemented in a commercial finite element code. The capabilities of the model are demonstrated.
