Abstract

Directionally solidified materials are being increasingly used in aircraft engines. These alloys are anisotropic due to the well aligned crystalline structure with additional considerations including large grain sizes and perturbations in the local orientation. In this paper, the Bishop-Hill method is combined with nonlinear optimization techniques to predict the anisotropic plastic behavior of an ideal directionally solidified FCC material subjected to off-axis uniaxial loadings. A comparison of these results is made with a continuum theory.
