plastic strain
[/ˈplæstɪk streɪn/]
nounpl: plastic strains
deformação plástica
1. The permanent deformation of a material that occurs when stress exceeds the material's yield point, resulting in permanent shape change that does not recover when the stress is removed
The metal beam experienced plastic strain after the heavy load was applied, and it did not return to its original shape.
A viga de metal sofreu deformação plástica após a carga pesada ser aplicada, e não retornou à sua forma original.
2. In materials science and engineering, the irreversible component of total strain in a material following stress application
Engineers calculated the plastic strain to ensure the structure could withstand repeated loading cycles.
Os engenheiros calcularam a deformação plástica para garantir que a estrutura pudesse suportar ciclos de carregamento repetidos.
This is a specialized technical term primarily used in engineering, materials science, and physics contexts in both Brazil and the USA. It is fundamental to understanding material behavior in construction, manufacturing, and mechanical design. The concept is taught in engineering programs worldwide and is essential for ensuring structural safety and durability.
