deviatoric component
[/ˌdeviəˈtɔːrɪk kəmˈpoʊnənt/]
nounpl: deviatoric components
componente desviadora
1. In mechanics and materials science, the part of the stress tensor that represents shape changes without volume change, obtained by subtracting the hydrostatic (mean) stress from the total stress
The deviatoric component of the stress tensor is responsible for shear deformation in the material.
A componente desviadora do tensor de tensão é responsável pela deformação de cisalhamento no material.
2. The portion of strain or deformation that causes distortion of shape rather than change in volume
Engineers analyze the deviatoric component to understand how materials fail under shear stress.
Engenheiros analisam a componente desviadora para compreender como os materiais falham sob tensão de cisalhamento.
This is a specialized technical term primarily used in engineering, materials science, soil mechanics, and continuum mechanics. It is found in academic and professional contexts in both Brazil and Portugal, particularly in university engineering programs and research institutions. The term is language-independent in international scientific publications.
