围动力学（PD）是模拟土木工程中不连续问题的有力方法。然而，要将材料本构模型应用到PD程序中，以解决广泛的问题，可能需要付出大量的努力。OpenSees是一个开源软件，它包含一个通用的材料库，已经被土木工程的研究人员和工程师广泛使用。在此背景下，本文提出了一种简单而有效的方法，利用客户端-服务器（Client-Server， CS）软件集成技术将PD与OpenSees集成，使PD可以直接使用OpenSees中已有的材料本构模型。提出了两个应用程序来验证新的PD-OpenSees平台。采用三维多屈服面塑性模型模拟水平荷载作用下带预裂缝的板，采用三维Cap塑性模型模拟单轴荷载作用下带矩形孔的混凝土块。结果表明，无需将复杂的材料模型编译/链接到PD程序中，只需将PD与三维塑性本构模型相结合，即可分析弹塑性材料（如混凝土和土）裂纹的产生/扩展。因此，本文提出的集成PDOpenSees平台有可能解决土木工程中广泛的复杂问题。
Peridynamics (PD) is a powerful method to simulate the discontinuous problems in civil engineering. However, it may take a lot of effort to implement the material constitutive models into PD program for solving a broad range of problems. OpenSees is an open source software which includes a versatile material library and has been widely used by researchers and engineers in civil engineering. In this context, the paper presents a simple but effective approach to integrate PD with OpenSees by using a Client-Server (CS) software integration technique, such that the existing material constitutive models in OpenSees can be directly used by PD. Two applications are presented to verify the new PD-OpenSees platform. The first one is a plate with a pre-crack subject to horizontal load simulated using a three-dimension (3D) multi-yield-surfaces plasticity model, and the second one is a concrete block with a rectangular hole subject to a uniaxial loading condition simulated using a 3D Cap plasticity model. It shows that the generation/ propagation of cracks of the elastoplastic materials (e.g., concrete and soil) can be analyzed by combing PD and three-dimensional plasticity constitutive models without compiling/ linking these complex material models into PD program. Thus, the integrated PDOpenSees platform presented herein is potentially capable to solve a wide range of complex problems in civil engineering.
