The dual variable FEM formulation can avoid the difficulty of C1 continuitycondition.
对偶变量有限元推导可避免所谓的C1连续性问题。
2
The continuitycondition across the interface between two materials is studied. Rationality of the results is analysed.
还研究了两种材料粘结界面处的连续条件，分析了结果的合理性。
3
A new stress element near a hole which satisfies both the stress boundary conditions at the hole and at the surface of the laminate and stress continuitycondition at the interface is developed.
