The fracture problem in gears with cracks on the root of the gear teethes has been considered in this article. The problem was solved by the finite element method, using the ABAQUS software. Then, the stress intensity factor at the tip of cracks was calculated for different loading conditions. The stress intensity factor at the tip of cracks for steel gears and gears made of functionally graded materials were obtained and compared. The position of the indentation load, the geometry of the tooth root and the tooth flank load distribution on the stress intensity factor was investigated. Numerical results showed that by considering the size of the crack in the tooth root, the value of the stress intensity factor, mode I, was bigger than mode II and mode III.
