Abstract: A quasi-quasi-principal axis frame means a unit orthogonal frame in which the shear strains are small. As an extension of Hill’s principal axis method we establish the approximate representations for various strains. the.finite rotation tensor, spins, strain rates. conjugate stresses and their rates with respect to quasi-principal axes. The quasiprincipal axis method may function as a new basis of numerically analyzing finite deformation problems.

Key words: small shear strain, quasi-principal axes, applied large deformation method
