  2. Constitutive equation - Wikipedia

    en.wikipedia.org/wiki/Constitutive_equation

    The first constitutive equation (constitutive law) was developed by Robert Hooke and is known as Hooke's law.It deals with the case of linear elastic materials.Following this discovery, this type of equation, often called a "stress-strain relation" in this example, but also called a "constitutive assumption" or an "equation of state" was commonly used.

  3. Symbolab - Wikipedia

    en.wikipedia.org/wiki/Symbolab

    Symbolab is an answer engine [1] that provides step-by-step solutions to mathematical problems in a range of subjects. [2] It was originally developed by Israeli start-up company EqsQuest Ltd., under whom it was released for public use in 2011. In 2020, the company was acquired by American educational technology website Course Hero. [3] [4]

  4. Material point method - Wikipedia

    en.wikipedia.org/wiki/Material_Point_Method

    Variables on the material points: positions, velocities, strains, stresses etc. are then updated with these rates depending on integration scheme of choice and a suitable constitutive model. Resetting of grid. Now that the material points are fully updated at the next time step, the grid is reset to allow for the next time step to begin.

  5. Viscosity models for mixtures - Wikipedia

    en.wikipedia.org/wiki/Viscosity_models_for_mixtures

    The viscosity is not a material constant, but a material property that depends on temperature, pressure, fluid mixture composition, local velocity variations. This functional relationship is described by a mathematical viscosity model called a constitutive equation which is usually far more complex than the defining equation of shear viscosity ...

  6. Terrace ledge kink model - Wikipedia

    en.wikipedia.org/wiki/Terrace_ledge_kink_model

    In chemistry, the terrace ledge kink (TLK) model, which is also referred to as the terrace step kink (TSK) model, describes the thermodynamics of crystal surface formation and transformation, as well as the energetics of surface defect formation. It is based upon the idea that the energy of an atom’s position on a crystal surface is ...

  7. Cauchy elastic material - Wikipedia

    en.wikipedia.org/wiki/Cauchy_elastic_material

    This definition assumes that the effect of temperature can be ignored, and the body is homogeneous. This is the constitutive equation for a Cauchy-elastic material. Note that the function depends on the choice of reference configuration. Typically, the reference configuration is taken as the relaxed (zero-stress) configuration, but need not be.

  8. Lists of physics equations - Wikipedia

    en.wikipedia.org/wiki/Lists_of_physics_equations

    In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.

  9. Hypoelastic material - Wikipedia

    en.wikipedia.org/wiki/Hypoelastic_material

    In continuum mechanics, a hypoelastic material [1] is an elastic material that has a constitutive model independent of finite strain measures except in the linearized case. . Hypoelastic material models are distinct from hyperelastic material models (or standard elasticity models) in that, except under special circumstances, they cannot be derived from a strain energy density fun
