- 摘要：
- A criterion is proposed first to quantitatively check the interpolation precision of quadrilateral elements. With
this criterion, the necessary geometry constraints are derived for 8-node (Q8) element to exactly attain quadratic
interpolation precision. The study is next to focus on improvement of the Q8 element with a bilinear configuration
and the Q8 element is subsequently presented by slightly modifying the Q8 element. Theoretical analysis is
conducted as well to confirm the interpolation precision predicted in the Q8 element. Through typical numerical
examples, it is concluded that of all the tested elements the second-order integrated Q8 element is the most robust
one for all cases.
