  2. Besides, the gauss interpolation function and the domain of support which includes much more nodal information than finite element method does is used to make meshless method much more earlier solve the large deformation and distortion and describe the local characteristic ( such as stress locality et al. ) more facilely

    並由於在無法中採用了高次插值函數和包含有較多節點的支持域(在有限元法中的支持域只包含單元節點) ,從而使得無法能方便地處理和應力應局部化等問題。
  3. Thirdly, zero energy - error is introduced and used to optimize combined hybrid axisymmetric finite elements through adjusting the combined factor. the influence of combined factor on axisymmetric elements is discussed. finally, the main points of the whole paper are summed up and some further thoughts are put forward

    數值實驗結果表明:能量協調和近似能量協調的軸對稱元都具有高精度、不發生poissonlocking和對不敏感的特點;經過優化之後的軸對稱元性能能夠得到進一步改善。
  4. Numerical results all indicate that the two axisymmetric finite elements exhibit better numerical precision, excellent performance at the nearly incompressible limit and distortions of the element geometry, and element performances are improved after optimization. the layout of this thesis is follows

    具體表現是:對有很好的適應性;計算可靠,不發生poissonlocking現象;對雙線性等參元的粗精度有很好的改善。
