WebThe Right Cauchy-Green Deformation Tensor The tensor is termed the right Cauchy-Green deformation tensor. As shown above, it is a positive definite symmetric matrix, thus, it has three positive real eigenvalues and three perpendicular eigenvectors. WebIn continuum mechanics, stress is a physical quantity that describes forces present during deformation. An object being pulled apart, such as a stretched elastic band, is subject to tensile stress and may undergo elongation. An object being pushed together, such as a crumpled sponge, is subject to compressive stress and may undergo shortening. The …

WebThis result is known as Cauchy’s theorem and yields how any initial line element is changed in magnitude and orientation by the time-dependent deformation tensor F. The short derivation presented here may be helpful to readers to see the origin of this idea. Below we indicate the extension of these ideas to second-rank tensors, such as 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
