inelastic sections
[ɪn-ɪ-ˈlas-tɪk ˈsek-ʃənz]
nounpl: inelastic sections
seções inelásticas
1. In structural engineering and material science, portions of a structural member or material that do not return to their original shape or size after deformation, experiencing permanent plastic deformation when stress is applied beyond the elastic limit
The inelastic sections of the steel beam showed permanent deformation after the load test exceeded its yield strength.
As seções inelásticas da viga de aço apresentaram deformação permanente após o teste de carga exceder seu limite de escoamento.
2. Regions within a structural element where material behavior is characterized by non-linear stress-strain relationships and permanent strain accumulation
Engineers must account for inelastic sections when designing structures to withstand earthquakes.
Os engenheiros devem levar em conta as seções inelásticas ao projetar estruturas para resistir a terremotos.
This is a highly technical term primarily used in civil engineering, structural mechanics, and materials science education and professional practice in both Brazil and Portugal. It's commonly encountered in university engineering curricula and structural design codes. The term reflects the international standardization of engineering terminology across Portuguese-speaking countries.
