1. A feature or discontinuity in a material or structure that causes a local increase in stress concentration, typically reducing the material's load-bearing capacity
The sharp corner in the metal bracket acts as a stress raiser, making it prone to crack initiation.
O canto agudo no suporte de metal atua como um concentrador de tensão, tornando-o propenso à iniciação de trincas.
2. In engineering and materials science, any geometric or material irregularity that amplifies stress at that location
Notches, holes, and fillets can all serve as stress raisers in mechanical components.
Entalhes, furos e concordâncias podem servir como concentradores de tensão em componentes mecânicos.
