摘要: By using Cayley-Hamilton theorem,two kinds of explicit representation for th e rotation tensor are proposed.One contains the lower powers of deformation gradient,by which the formula of the principal rotation angle and the explicit representation of principal axis are obtained;the other,a high efficient method to obtain th e rotation tensor,does not contain the complicated coefficients and u ses few variables.Some properties about the principal rotation angle and the principal rotation axis are obtained.
