1. A condition in which stress components are equal in all directions, typically represented as a hydrostatic or mean stress with no shear stress components.
Under an isotropic stress state, the material experiences uniform compression or tension from all directions.
Sob um estado de tensão isotrópico, o material sofre compressão ou tração uniforme de todas as direções.
2. In continuum mechanics, a stress state where the stress tensor has equal principal stresses and zero shear stresses on all planes.
The isotropic stress state simplifies calculations in materials testing.
O estado de tensão isotrópico simplifica os cálculos nos testes de materiais.
