| 摘 要： | 采用参考单元模型实现了板（壳）单元在厚度方向上的准联接。克服了一般板（壳）单元难以模拟分层前沿处力学机制的困难。对典型分层损伤问题给出的数值算例表明，该模型对分层损伤的后屈曲分析是准确的和收敛的。该模型的特点在于简洁和实用性。

| Abstract: | The quasi connection along the thickness direction is completed and the difficulty of simulating the delaminated front that the general plate/shell element can not deal with is also solved by using reference surface method in delaminated plate/shell problems. Several typical numerical examples, which verify the accuracy and convergence of this method using for post buckling analysis of delaminated plate/shell, are presented. The characters of this model are of simplicity and practice. |
