The sensitivity of isoparametric elements to mesh distortions has not been sufficiently addressed. Based on the generalized H-R variational principle, the formula of the hexahedral volume coordinate mixed method (HVMM) is derived which applies volume coordinates as local coordinates, maintaining a linear relationship with the Cartesian coordinate system. The influence of the stress boundary conditions on the stress results is also discussed. Numerical results demonstrate the superiority of the proposed element against mesh distortion, and the accuracy of stress results is higher than that of the hexahedral volume coordinate method element (HVCC8) and other displacement elements.
