1. A geometric feature or irregularity in a material that causes an increase in local stress concentration, reducing the strength and fatigue resistance of the component
The sharp corner acts as a stress riser, making the component more prone to failure.
O canto agudo funciona como um concentrador de tensão, tornando o componente mais propenso a falha.
2. Any discontinuity, notch, hole, or change in cross-section that elevates stress levels beyond the nominal applied stress
Engineering designs must minimize stress risers to improve durability.
Os projetos de engenharia devem minimizar os concentradores de tensão para melhorar a durabilidade.
