Influence of error of determination of moire isotach orders on the stability of their approximation
Abstract
A check is made of the stability of approximation of moire isotachs from a formula proposed in a previous work. The relative errors of the calculated values for the flow speeds at the center and edges of a moire band, neglecting rigid translation of the metal, do not exceed 3.5%. The highest error lies in the calculated values for the tensor components of the deformation speeds at the beginning and end of the deformation zone, namely 10%.
