Abstract:

The relative error in energy can be estimated on the basis of the asmptotic estimate ot thte rate of p-convergence. Nearly optimal control of error can be achieved when feedback information, generated from p-convergence data, is used for deciding whether the mesh should be refined or the polynomial degree of elements increased. Partial Contents Convergence in energy norm Problems with smooth solutions Problems with stress singularities and Estimates of error in energy norm.
