Plastic stress, residual stress, alloyed and high strength materials, Holloman Equation and Hooke’s EquationResumo
This paper presents the applied stress, the residual stress and difference between them for two different materials, calculated by the combination of Hooke´s Law and Holloman Law. In order to calculate the stresses two different materials were chosen, the first is an alloyed steel SAE 4340 and the second a high strength steel UHB-20C. The results showed that both materials showed the same trend, which means the difference between the applied stress and the residual stress is minimal when applied stress is closer to material tensile strength. On contrary, when the applied stress is closer to the materials yield strength the difference is significantly higher.
