Commutativity of the strain energy density expression for the benefit of the FEM implementation of Koiter's initial postbuckling theory

The concept of full commutativity of displacements in the expression for strain energy density for the geometrically nonlinear problem has been introduced for the first time and fully established in this paper. Its consequences for the FEM formulation have been demonstrated. As a result, the strain...
