“…The last one connects stress value with material temperature during plastic deformation Johnson-Cook plasticity model provides an accurate description of plastic strain related to high strain rates, even without considering variations in elastic properties. 17 Crash elements in automobiles are generally produced from materials with high energy absorbing ability. Aluminum alloys and steels are preferred as crashing elements due to their high energy absorption capabilities in collisions.…”

“…Entretanto, esses mesmos autores pontuaram que, nos testes experimentais, o modo de deformação octogonal ocorria raramente e era muito sensível às imperfeições geométricas de fabricação. Em concordância com os resultados dessas pesquisas, em estudos recentes, realizados por Maia (2021) e Ascensão (2022), ao se analisar os efeitos de diferentes técnicas de soldagem empregadas na junção de crash boxes tipo origami, também foi "TEMA DO 23º CONEMI: Alternativas energéticas, sustentabilidade e impactos para as gerações futuras. "…”
