Abstract: This paper studies the computational efficiency andaccuracy of the eight-node hexahedral combined hybrid element (CHH (0-1)), and the reliability of data from ANSYS software.The bending plate model is taken as a test problem to be solved by CHH (0-1)element, 8-node brick element and 20-node brick element in ANSYSsoftware,respectively. A comparison of the displacement and stress results shows that the so-called 8-node brickelement in ANSYS software is the Wilson brick element actually, which gives reliable displacement results, but its computational accuracyfor stress is poor. The 20-node brick element is very time-consumingand the computational accuracy of stress results is not so good. But CHH(0-1) element can achieve a high-precision for both displacement and stresswith less cost.
