yield point test
[/ˈjɪld pɔɪnt tɛst/]
nounpl: yield point tests
teste de limite de escoamento
1. A mechanical test used to determine the yield point of a material, which is the stress level at which a material begins to deform plastically
The yield point test confirmed that the steel could withstand stresses up to 300 MPa before permanent deformation occurred.
O teste de limite de escoamento confirmou que o aço poderia suportar tensões de até 300 MPa antes de ocorrer deformação permanente.
2. A standardized procedure in materials science and engineering to measure the point at which elastic deformation transitions to plastic deformation
Engineers performed a yield point test on the aluminum alloy to ensure it met safety specifications.
Os engenheiros realizaram um teste de limite de escoamento na liga de alumínio para garantir que atendesse às especificações de segurança.
The yield point test is fundamental in both American and Brazilian engineering standards for quality control and safety certification of materials. In Brazil, it is commonly performed in metallurgical laboratories and construction companies. The terminology may vary slightly between European and Brazilian Portuguese, with Portugal using 'cedência' while Brazil typically uses 'escoamento'.
