The corrosion of structures is needed to be identified early to prevent any severe damage of buildings. The conventional technique such as potential mapping for diagnosing of reinforced concrete corrosion has been used widely in the field. However, the method has limitation such as less accuracy, laborious and time-consuming. This study is conducted to develop boundary element method 3 dimensions by considering polarization curves of anode and cathode for corrosion simulation and analyzed the influences of anode profiles for RC corrosion simulation. In this method, the potential in concrete domain was modeled by Laplace’s equation. The anode and cathode areas were represented by each polarization curves. The numerical simulation result shows that the boundary element method 3 dimensions successfully solved the Laplace’s equation in order to simulate corrosion phenomenon of reinforced concrete. The influences of anode profiles for RC corrosion simulation have been analyzed. Further works are needed to reduce the computational effort of corrosion simulation.

For obtain the effect of floating ring radius R2 and floating ring velocity v2 on internal friction in dislocated floating ring with different eccentricities, the evolution of internal friction is simulated with boundary element method (BEM). Numerical simulation results show that internal friction increases with the increase of eccentricity. Internal friction rises linearly as the addition of floating ring velocity v2 if the eccentricity e and radius R2 are fixed. When the velocity v2 is a constant and the range of R2 is 0.75<R2<0.8, the internal friction increase enormously.
