viscoplastic deformation
[ˌvɪs.koʊˈplæs.tɪk ˌdɛf.ərˈmeɪ.ʃən]
nounfemininepl: viscoplastic deformations / deformações viscoplásticas
deformação viscoplástica
1. A permanent deformation of a material that exhibits both viscous (time-dependent) and plastic (permanent) behavior when subjected to stress, occurring at temperatures where the material exhibits creep characteristics combined with permanent strain without returning to its original shape
The viscoplastic deformation of the metal increased significantly when heated above its transition temperature.
A deformação viscoplástica do metal aumentou significativamente quando aquecido acima de sua temperatura de transição.
2. In materials science, the inelastic strain that combines the rate-dependent behavior of viscous flow with the irreversible nature of plastic deformation
Engineers must account for viscoplastic deformation when designing components that operate at elevated temperatures.
Os engenheiros devem considerar a deformação viscoplástica ao projetar componentes que operam em temperaturas elevadas.
This is a specialized technical term primarily used in materials science, mechanical engineering, and metallurgy. It is not region-specific within Brazil or the USA, as it is standardized terminology in academic and industrial contexts. The term is essential in high-temperature material research, aerospace engineering, and manufacturing processes where materials undergo both time-dependent and permanent deformation under sustained stress.
