The paper examines the properties that constraint manifolds possess as Riemannian submanifolds of the Euclidean space of all second-order tensors and have implications on the description of mechanical behavior of internally constrained bodies. It is shown that constraint manifolds corresponding to some usual internal constraints have non-zero curvature and, hence, possess a non-Euclidean structure that has to be taken into account when the active and reactive parts of the Piola-Kirchhoff stress are differentiated with respect to deformation gradient. -

Abstract

The paper examines the properties that constraint manifolds possess as Riemannian submanifolds of the Euclidean space of all second-order tensors and have implications on the description of mechanical behavior of internally constrained bodies. It is shown that constraint manifolds corresponding to some usual internal constraints have non-zero curvature and, hence, possess a non-Euclidean structure that has to be taken into account when the active and reactive parts of the Piola-Kirchhoff stress are differentiated with respect to deformation gradient. -
