1. The maximum stress level below which a material can theoretically endure an infinite number of stress cycles without failing
The fatigue limit of this steel alloy is approximately 300 MPa.
O limite de fadiga desta liga de aço é aproximadamente 300 MPa.
2. In materials science, the stress amplitude below which no fatigue failure will occur regardless of the number of loading cycles
Engineers must design components to operate below the fatigue limit to ensure long-term reliability.
Os engenheiros devem projetar componentes para funcionar abaixo do limite de fadiga para garantir confiabilidade a longo prazo.
