Right cauchy green tensor
WebNov 20, 2024 · The Cauchy-Green tensors are not strain measures. They do not reduce to the infinitesimal strain tensor in the limit of small displacements. However, the CG tensor … WebThe stress tensor which naturally derives from Edescribes the surface force measured in the initial space with respect to the initial area: dF0=da = @E=@", it is known as the second Piola-Kirchho stress. Then in order to nd the Cauchy stress measured fully in the target space: ˙= dF=dA, we need to transform the surface force and the area as

They are single-based second-order tensors, either Eulerian or Lagrangian, and are defined in terms of the Cauchy-Green deformation tensors, which are derived from the deformation gradient. The Green-Lagrange strain tensor is Lagrangian based, while the ...
Webwhere S stands for the PK2 stress tensor, E is the Green-Lagrange strain tensor, and C is the right Cauchy-Green stretch tensor. The strain energy density is a non-negative scalar-valued function of a tensorial strain measure. It vanishes during a rigid body motion if the media is initially in a stress-free configuration, leading to the so ...
