Calculation of the thermal stress and thermal resistance of anisotropic materials. II

Journal Article:

Abstract

The stressed state in a wedge and in a family of plates cut from single-crystal ingots of 40 axial orientations is analyzed. It is shown that, in contrast to the case of the wedge, the value of the thermal stress tensor components in the plates depends substantially not only on the axial crystallographic orientation but also on the azimuthal orientation. Requirements on the crystallographic orientation of simple single-crystal parts of plate or wedge type are formulated with the aim of decreasing the detrimental effects of thermal stresses. The correctness of the calculations is confirmed by results of thermal fatigue tests of hollow prismatic specimens, i.e., blade simulators with 001, 011, and 111 axial orientations.
