Finite amplitude oscillatory shear experiments are used to study the mechanical behavior of viscoelastic materials. Four rheological relations are derived which can be used to determine both linear and nonlinear rheological properties of simple fluids from data obtained using large amplitude oscillatory experiments. Two consistency conditions are derived for a fluid which obeys the K-BKZ constitutive equation, and these relations are used in conjunction with data from a finite amplitude oscillatory experiment to check the validity of the K-BKZ equation.
