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.
A governing equation may also be a state equation, an equation describing the state of the system, and thus actually be a constitutive equation that has "stepped up the ranks" because the model in question was not meant to include a time-dependent term in the equation.
Constitutive may refer to: In physics, a constitutive equation is a relation between two physical quantities In ecology , a constitutive defense is one that is always active, as opposed to an inducible defense
Schematic diagram of Burgers material, Maxwell representation. Given that one Maxwell material has an elasticity and viscosity , and the other Maxwell material has an elasticity and viscosity , the Burgers model has the constitutive equation
The constitutive equations describe how the quantity in question responds to various stimuli via transport. Prominent examples include Fourier's law of heat conduction and the Navier–Stokes equations , which describe, respectively, the response of heat flux to temperature gradients and the relationship between fluid flux and the forces ...
Psychology Today is an American media organization with a focus on psychology and human behavior. The publication began as a bimonthly magazine, which first appeared in 1967. The print magazine's reported circulation is 275,000 as of 2023. [ 2 ]
The equation explains that autonomous agents (information, ideas or things) following simple rules (D,S,R,P) with their elemental pairs (i-o, p-w, a-r, ρ-v) in nonlinear order (:) and with various co-implications of the rules ( ), the collective dynamics of which over a time series j to n leads to the emergence of what we might refer to as ...
The equation was proposed as an attempt to unify the different branches of psychology (e.g. child psychology, animal psychology, psychopathology) with a flexible theory applicable to all distinct branches of psychology. [3] This equation is directly related to Lewin's field theory.
