In the present context the variation is performed keeping the deformed configuration fixed, while a suitable material stress tensor S and the material coordinates are required to vary independently from one another. The variational principle turns out to be equivalent to an equilibrium problem of placements and tractions at the boundary of a body of finite extent.

Abstract
In the present context the variation is performed keeping the deformed configuration fixed, while a suitable material stress tensor S and the material coordinates are required to vary independently from one another. The variational principle turns out to be equivalent to an equilibrium problem of placements and tractions at the boundary of a body of finite extent.File in questo prodotto:
