摘要:
采用通用有限元程序ANSYS 10.0对拔出试件进行了接触分析,对数值模拟中的材料模型定义、有限元模型的建立、接触单元生成及后处理等关键技术进行了系统的研究; 重点介绍了使用Targe170和Conta174单元建立三维接触对的实用方法,建议了库仑摩擦模型中摩擦因数和胶着强度的取值,最终实现了基于ANSYS接触分析的粘结-滑移数值模拟。结果表明:该方法可对钢筋拔出过程中的接触摩擦力、接触压力及接触状态等问题进行研究,弥补了宏观试验的不足,模拟拔出试验中的粘结-滑移关系具有一定的可行性。
Abstract:
Contact analysis of pull-out specimen was carried out by using finite element program ANSYS 10.0. A series of numerical simulation techniques, such as defining material model, establishing finite element model(FEM), generating contact element and post-processing were studied. The practical method of setting up 3-D contact pair with element Targe170 and Conta174 was emphatically introduced. Both friction coefficients of Coulomb friction model and adhesion strength were recommended. Finally, bond-slip numerical simulation was achieved based on ANSYS contact analysis. Results show that contact friction, contact pressure and contact state in the process of steel bar pull-out can be studied by this method, which makes up the deficiency of macro test. This method is feasible to simulate bond-slip relationship during pull-out test.
