Around the close of the nineteenth century, the development of a braking system for newly manufactured automobiles was necessary. This equipment, which contains several components (including the brake disc), has been developed since then. The brake system's technological progress took off with the commencement of the Second World War, in 1938, due to the necessity of the aeronautics industry. Gray cast iron was the first material used to make brake discs because it possesses excellent thermal conductivity, corrosion resistance, low noise, low weight, long durability, constant friction, low wear rate, and a favorable price/benefit ratio. As a result, a number of materials have been developed for this purpose during the last century, but gray cast iron, which is affordable and simple to produce, is the most commonly utilized. The modeling of fatigue strength of gray cast iron alloys is gaining a lot of attention right now in order to enhance the component's service life. Although this sort of analysis yields important results, they must be confirmed by experimental research, which implies the component must be studied in real-world rather than virtual circumstances.
