The reliability of a railway braking system is strongly influenced by the material selection and geometric design of the brake block, which determine the stress distribution during operation. The problem faced is the limited number of studies that simultaneously analyze the effect of material combinations and design variations on the maximum stress response. Previous studies generally examined materials or geometries separately, so an integrated analysis is still needed. This study aims to analyze the effect of the T358 design and the Chinese reference design, as well as the combination of nodular cast iron and magnetic composite materials, on the maximum stress value. The method used is a finite element simulation with a load of 4173.8 N, where the simulation results are validated by comparing trends with previous studies to ensure the suitability of the stress distribution behavior. The results show the safest condition in the Chinese design with a 75% magnetic composite composition of 0.1603 MPa, while the most critical condition occurs in the 75% nodular cast iron composition. In conclusion, the combination of materials and geometry has a significant effect on the maximum stress, and further research is recommended to examine layer variations in magnetic composites for performance optimization.
