Abstract: It is considered the relationships for the Green-Lagrange strain tensor in curvilinear orthogonal coordinates exactly representing arbitrarily large rigid-body motions. This consideration is based on the kinematic Timoshenko hypothesis adopted for every layer of the shell (piece-wise linear approximation).
