The most critical elements of the safety systems in a vehicle are found in the brake system. The brake disc, one of the elements of this system, is the system element that is most exposed to external factors. In this study, fatigue analysis was carried out with three different disc designs (solid, perforated, and slotted) and two different materials (structural steel and AISI 4340 steel), considering the brake disc design dimensions of light commercial vehicles. After designing the disk designs through a computer-aided design program, they were first subjected to static and then fatigue analysis with the help of ANSYS sub-module fatigue analysis. The results were made using the finite element method and are presented as total deformation, equivalent stress, safety factor, life, and damage values. In the total deformation results, the structural steel material perforated design disk has the lowest value with 0.018 mm deformation, while the AISI 4340 material solid design disk has the lowest value with 49.477 MPa in the equivalent stress result values. In terms of damage results, solid and perforated design discs made of AISI 4340 steel have reached a value of one-tenth of the closest design. In life cycle comparison, the AISI 4340 steel material solid disk design has 1.41 times more cycles than the closest value, the AISI 4340 steel material perforated disk design. In terms of safety factor values, the structural steel material solid disk design was 1.13 times higher than the structural steel material perforated disk design, which has the closest value. In the overall evaluation of the analysis results, it was understood that the solid disk design with AISI 4340 material was the most suitable solution in the design, taking into account fatigue
