[/ˌkɑːnstɪˈtjuːtɪv ˈmɑːdəl/]
nounpl: constitutive models
modelo constitutivo
1. A mathematical representation that describes the relationship between stress and strain in a material under applied loads, characterizing how the material deforms and responds to mechanical forces
The engineer selected an elastic-plastic constitutive model to simulate the material behavior during the crash test.
O engenheiro selecionou um modelo constitutivo elástico-plástico para simular o comportamento do material durante o teste de colisão.
2. In materials science and mechanics, a mathematical framework that defines the internal properties and behavior of a material substance
A nonlinear constitutive model is required to accurately predict soil behavior under seismic loading.
Um modelo constitutivo não-linear é necessário para prever com precisão o comportamento do solo sob carregamento sísmico.
This is technical terminology widely used in international engineering, materials science, and structural analysis communities. Both Brazilian and Portuguese engineers employ the same term 'modelo constitutivo' in academic and professional contexts. The term is essential in computational mechanics, finite element method applications, and material characterization studies across both English and Portuguese-speaking countries.
