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.
