摘要: 对薄层单元的基本假设和简化进行了探讨并得到如下结论:薄层单元的本构方程可 通过横观各向同性体本构方程采用合理简化得到;薄层单元受拉开裂的本构关系可 采用分布裂缝模型模拟开裂简化得到;薄层单元采用的基本假 设能在一定程度上保证计算精度及简化计算.

Abstract: This paper discusses fundamental assumption and simplification of the thin-layer element. The thin-layer element constitutive model can be obtained from the constitutive model of transversely isotropic materials. The constitutive relation of thin-layer elements in crak can be obtained by using the distributed crack model. The fundamental assumption of thin-layer elements can assure calculation accuracy and simplify calculation to a certain extent.
