We consider the systematic calculation of higher-order-accuracy points in ®nite element analysis. The cases of varying material properties and distortion of elements are included. The results obtained are used to establish an error estimator that is element-based and applicable to varying material properties. Some example problems are solved and show the applicability of the error estimator. While one-dimensional problems are studied in detail, the extension to two-and three-dimensional… CONTINUE READING
