这项工作扩展和推广了最近开发的流固耦合计算框架，以建模和模拟流体诱导的故障和断裂。特别是，提出了一种新的表面表示方法来表示的背景下，嵌入边界法的流体-结构界面的断裂。这种方法是通用的，因为它适用于许多不同的计算断裂模型和方法，包括单元删除（艾德）技术和扩展有限元法（XFEM）。两个三维模型问题展示了计算框架的显著特征，并比较了艾德和XFEM在流体诱导失效和断裂方面的性能。Copyright © 2015 by ASME
This work extends and generalizes a recently developed fluid-structure coupled computational framework to model and simulate fluid-induced failure and fracture. In particular, a novel surface representation approach is proposed to represent a fractured fluid-structure interface in the context of embedded boundary method. This approach is generic in the sense that it is applicable to many different computational fracture models and methods, including the element deletion (ED) technique and the extended finite element method (XFEM). Two three-dimensional model problems are presented to demonstrate the salient features of the computational framework, and to compare the performance of ED and XFEM in the context of fluid-induced failure and fracture.Copyright © 2015 by ASME
