| Abstract: | This paper presents the model of 4-node,6-node and 8-node three dimension transitionisoparametric elements,derives their stress smoothing formula and generates computing pro-gram. The illustrative examples include elastoplastic problem and contact problem. The re-sults demonstrate the numerical accuracy and computational efficiency. |
