Abstract

Although it is widely known that small errors in d0 produce large errors in calculated components of the triaxial stress tensor, the magnitude and sign of errors in the elastic constants and do has not, thus tar, been visualized. In this study, the combined and isolated effects of errors on the resultant stress calculation is shown via three-dimensional, topographical, and onedimensional graphics. It has been found that stress is most sensitive to errors in d0, and least sensitive to S1. In most cases, errors lead to calculated stresses that differ from the true values by more than 20%, and in the worst cases change the magnitude by more than 200% and may even change the sign.
