Single Crystal Uniaxial Stress Experiments
An uniaxial stress experiment in a single crystal, whether dynamic or quasi-static, is complicated by the fact that such solids are anisotropic. Large deformation occurs as shear on preferred planes in specified directions. In a quasi-static experiment, the two axial measurements for the single crystal are the same as for the polycrystal, and in the field of large deformation may be determined with the same high degree of accuracy. Difficulties arise when the data from one quasi-static experiment are compared with the data from another. Unless the orientation of crystallographic axes with respect to the specimen axis is known, one may not meaningfully cross-compare data in any particular solid, let alone make comparisons between solids.
