我们提出了一个名为PERMIX的开源软件框架，用于固体中裂缝的多尺度建模和模拟。该框架是一个面向对象的开源项目，主要使用Fortran 2003标准编写，并通过Fortran/C++接口与许多其他库（如LAMMPS、ABAQUS、LS - DYNA和GMSH）相连。连续体层面的裂缝采用扩展有限元方法（XFEM）进行建模。通过使用几种新颖的或最先进的方法，该软件分别处理半并发多尺度方法以及用于裂缝的并发多尺度方法，将两个连续体域或原子域与连续体域耦合。我们的开源软件的效率通过几个模拟得以展示，包括粘土纳米复合材料中的三维裂缝建模、半并发有限元 - 有限元耦合、一个三维Arlequin多尺度示例以及用于动态裂缝扩展的分子动力学 - 扩展有限元耦合。
We present an open-source software framework called PERMIX for multiscale modeling and simulation of fracture in solids. The framework is an object oriented open-source effort written primarily in Fortran 2003 standard with Fortran/C++ interfaces to a number of other libraries such as LAMMPS, ABAQUS, LS-DYNA and GMSH. Fracture on the continuum level is modeled by the extended finite element method (XFEM). Using several novel or state of the art methods, the piece software handles semi-concurrent multiscale methods as well as concurrent multiscale methods for fracture, coupling two continuum domains or atomistic domains to continuum domains, respectively. The efficiency of our open-source software is shown through several simulations including a 3D crack modeling in clay nanocomposites, a semi-concurrent FE-FE coupling, a 3D Arlequin multiscale example and an MD-XFEM coupling for dynamic crack propagation.
