Conjugate stresses of the Seth–Hill strain tensors

In this paper, conjugate stresses of the Seth±Hill strain measures are treated by means of the de®nition of energy conjugacy and Hillʹs principal axis method. This approach results in relations between components of two di€erent conjugate stress tensors. The results are valid for distinct as well as coalescent principal stretches. Illustrative examples are solved to demonstrate the simplicity and usefulness of the derived relations between conjugate stress tensors
