Abstract

An isogeometrical approach, based on using the superconvergent property of the Gauss integration points, for ERROR ESTIMATION and STRESS RECOVERY of two-dimensional problems was introduced by Hassani et. al. In this paper, the method is further developed to deal with the isogeometrical analysis of three-dimensional problems. To investigate the performance of the approach in using the optimal stress points, two 3D examples with available analytical solutions are taken into consideration. The obtained results are indicative of the good performance of the method in improvement of stress and ERROR ESTIMATION of 3D PROBLEMS in the ISOGEOMETRIC ANALYSIS method.
