Abstract
By focusing on to what extent strain energies are approximated, this paper intends to derive the conditions for a discrete model to converge at the limit element division to the original finite-displacement elasticity. A criterion for that convergence is presented in a general form. Further, especial expansions are made to find out which discretized relations might be linearized at the limit. As a result, a natural classification of discretizations for finite-displacement small-strain problems is proposed.
