| 摘 要： | 本文以杂交／混事有限元为基础,讨论了壳单元“自锁”现象,论论了避免“自锁”的条件;指出与弯曲应力参数相耦合的膜应力参数和横剪应力参数对“自锁”现象不起任何作用。本文的结论可以推广到其他多变量有限元模型中。

| Abstract: | Basing on the hybrid/mixed finite element method the "locking" phenomenon in shell elements is discussed and the necessary conditions for access to locking free elements is proposed. As revealed, stresses coupled with those of bending stresses are practically of no significance in the locking phenomenon. Conclusions reached in the present paper can be extended to various multi-variable finite element models other than those involved hereinafter. |
