Through a computing transient thermal analysis, the team evaluated the quality of the material and its resistance to thermal fatigue by a comparative method. With the steel used in 1020 failed in 2014, for the team Formula UFMG, the 1020 steel, 1045, 1070 and stainless steel 304 were compared, where the stainless steel was the parameter of better resistance to thermal cracking.
The main calculated parameters were subjected to empiric validations and the best material has been applied and used in the 2015 season. The use of the disks in a competition and in a battery of tests superior to 2014, permitted the evaluation of the final result of applying the material.
