摘　　要：数值仿真试验作为土木工程试验的一个重要手段,越来越多地应用于土木水利类研究生的教学体系。将ABAQUS数值模拟技术引入土木工程有限元课程中“约束混凝土破坏特征”的教学内容,通过Python语言二次开发,借助VUMAT单元删除功能,建立约束混凝土破坏试验参数化仿真系统,实现荷载作用下约束混凝土破坏全过程模拟。通过试验数据分析与模拟结果对比,验证了数值仿真平台的合理性。学生可以通过该平台的交互式窗口输入数据实现自动建模分析,丰富了课程教学内容,为今后的实验教学提供了新思路。Numerical simulation test is an important tool in civil engineering experiments,and is used more and more in teaching systems for civil and hydraulic engineering graduate students.ABAQUS simulation technology is introduced into the finite element course of civil engineering for the teaching of“constrained concrete failure characteristics.”Python language is used for secondary development,and VUMAT unit deletion function is used to build a parameterized simulation system for constrained concrete failure tests.The system simulates the entire process of constrained concrete failure under load.The rationality of the simulation platform is verified by comparing test data analysis and simulation results.The platform allows graduate students to input data through interactive windows for automatic modeling analysis,enriching course content and providing new ideas for future experimental teaching.
