Abstract
In this paper, we investigate the anisotropic macroscopic behavior of single-crystal superalloy subjected to torsion loading. Two Viscoplast ic models are studied. One is a crystallographic approach based on Sch mid law, the second one is phenomenologically built up. Both models ar e implemented into finite element codes. Their predictive ability is c ompared through the results delivered by the F. E. calculations of cyl indrical specimens subjected to torsion. Results are also compared to the experiments.
