The relative power of actions in Cauchy bodies su¤ering mutations due to defect evolution is introduced. It is shown that its invariance under the action of the Euclidean group over the ambient space and the material space allows one to obtain (i) the balance of standard and conﬁgurational actions and (ii) the identiﬁcation of conﬁgurational ingredients from a unique source.
