Continuum Mechanicsberkeman said:What's cont. mech.?
Constitutive behavior refers to the response of a material to external forces or stimuli, such as stress, strain, and temperature. It is described by a set of equations that relate the material's internal state to its external behavior.
Material properties are intrinsic characteristics of a material, such as density, elasticity, and strength, while constitutive behavior describes how a material responds to external forces. Material properties are used to define constitutive behavior equations.
Understanding constitutive definitions allows scientists and engineers to accurately predict the behavior of materials under different conditions, which is crucial for designing and analyzing structures and systems.
Constitutive definitions can be determined experimentally by subjecting a material to different external forces and measuring its response. These data points are then used to develop equations that describe the material's behavior.
Yes, constitutive definitions can change for a material depending on factors such as temperature, strain rate, and microstructural changes. This is why it is important to understand and account for these variations in material behavior when using constitutive definitions in continuum mechanics.
