1. In engineering and materials science, the range of stress values within which a material or structural component can safely operate without permanent deformation or failure
The allowable stress region for this steel beam is between 0 and 250 MPa.
A região de tensão admissível para esta viga de aço é entre 0 e 250 MPa.
2. A graphical or mathematical domain that represents acceptable stress levels according to design codes and safety factors
Engineers must ensure that all operational stresses fall within the allowable stress region.
Os engenheiros devem garantir que todas as tensões operacionais fiquem dentro da região de tensão admissível.
