| Abstract |
The compatibility equation for the Cauchy-Green tensor field (squared tensor of pure extension with respect to the reference configuration) is directly derived from the well-known relation expressing this tensor via the vector field determining the mapping (transformation) of the reference configuration into the actual one. The derivation is based on the use of the apparatus of coordinate-free tensor calculus and does not apply any notions and relations of Riemannian geometry at all.
The method is illustrated by deriving the well-known compatibility equation for small strains. It is shown that when the obtained compatibility equation for finite strains is linearized, it becomes the compatibility equation for small strains which indirectly confirms its correctness. |
