摘　　要：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.
