Abaqus code for phase field fracture in elasto-plastic solids

Abaqus 2D and 3D UEL and UMAT subroutines for the phase-field modeling for fracture of elasto-plastic solids. The code consists of the 2-layered system of user elements and user material subroutine producing a staggered algorithm. The codes along with input files for three benchmark examples from the associated journal article are given. A tutorial is provided in the associated journal article.适用于弹塑性固体断裂相场建模的Abaqus二维、三维用户单元子程序（User Element Subroutine, UEL）与用户材料子程序（User Material Subroutine, UMAT）。该代码构建了两层用户单元与用户材料子程序体系，可实现交错求解算法。本代码附带相关期刊论文中三个基准算例的输入文件，相关期刊论文中还提供了配套使用教程。
