Abstract
Zero energy-error is used to optimize combined hybrid axisymmetric finite elements though adjusting the combined factor. These axisymmetric finite elements include eight-parameter energy compatibility axisymmetric finite element and complete linear stress interpolation axisymmetric finite element. Numerical results all indicate that energy compatibility axisymmetric finite element exhibits better numerical precision, excellent performance at the nearly incompressible limit and distortions of the element geometry, and element performances are improved after optimization.
