초록
This study was discussed with the friction effects due to surface roughness of the interface between the base material and a reinforcement at the downward inclined interfacial crack under shear loading. The fracture parameter are analyzed by finite element method of the ANSYS. As the friction coefficient of the surface is assumed zero and 0.3, the fracture is analyzed. This study was analyzed with inclination angles about 0 degrees, 45 degrees and 90 degrees. As the results, at the inclination angle of 0, the energy release rate is reduced by about 3%. About 16%, and 2% are decreased at 45 degree and 90 degree respectively. If the inclination angle is 45 degrees, the friction effect by the sliding resistance between the interface was found to be most effective.
