Abstract This study examines the performance of cast iron and stainless steel brake discs under varying loads and temperatures, with a focus on angular speed, radial stress, and circumferential stress. The results show that angular speed decreases with higher radii ratios and loads for both materials, with cast iron outperforming stainless steel due to its lower density and higher stiffness. Stainless steel exhibits higher radial stress and greater sensitivity to temperature changes. Circumferential stress decreases with the radii ratio, with stainless steel consistently showing higher stress levels, particularly at higher loads. Overall, cast iron is more efficient in maintaining angular speed, while stainless steel is more sensitive to stress and temperature variations.
