| 摘 要： | 给出了关于冰的粘弹性微分本构模型的广义变分原理和冰载荷计算的有限元方法。修正的增量粘弹性矩阵有效地加速了迭代过程，计算了瞬态温度场下冰内压应力分布及对结构物作用力。其结果与实测数据定性吻合。

| Abstract: | A generalized variational principle about a viscoelastic differential constitutive model of ice and thefinite element method to be used in the calculation of ice load are presented in this paper. The modifiedincremental visco-elastic matrix is also presented to speed convergence rate of iteratoin effectively.Compressive stresses distributed in ice which will act upon the structures as ice load under transienttemperature field are computed. The results are consistent with experimental date in principle. |
