Abstract:
The minimization of the discretization error corresponding to a given total number of nodes is considered for each one of the steps which may be considered in the application of the f. e. m. In what concerns the choice of the type of the element, the rule must be respected of the accuracy of the stresses being consistent with the accuracy of the displacements or tractions. In what concerns the topology of the mesh, it is shown that the best topology depends on the orientation of the mesh with respect to the isoenergetic lines. The problem of the best allocation of the nodes is also considered.
