Relaxation time — is a general concept in physics for the characteristic time in which a system changes to an equilibrium condition from a non equilibrium condition. It can measure the time dependent response of a system to well defined external stimuli.… … Wikipedia

Relaxation (physics) — In the physical sciences, relaxation usually means the return of a perturbed system into equilibrium. Each relaxation process can be characterized by a relaxation time τ. The simplest theoretical description of relaxation as function of time t is … Wikipedia
Relaxation technique — A Relaxation technique (also known as Relaxation training) is any method, process, procedure, or activity that helps a person to relax; to attain a state of increased calmness; or otherwise reduce levels of anxiety, stress or tension. Relaxation… … Wikipedia
Relaxation oscillator — A relaxation oscillator is an oscillator in which a capacitor is charged gradually and then discharged rapidly. It is usually implemented with a resistor or current source, a capacitor, and a threshold device such as a neon lamp, diac,… … Wikipedia
Havriliak-Negami relaxation — is an empirical modification of the Debye relaxation model, accounting for the asymmetry and broadness of the dielectric dispersion curve. The model was first used to describe the dielectric relaxation of some polymersfn|1, by adding two… … Wikipedia
Debye relaxation — is the dielectric relaxation response of an ideal, noninteracting population of dipoles to an alternating external electric field. It is usually expressed in the complex permittivity varepsilon of a medium as a function of the field s frequency… … Wikipedia
Stress relaxation — describes how polymers relieve stress under constant strain. Because they are viscoelastic, polymers behave in a nonlinear, non Hookean fashion.Meyers and Chawla. Mechanical Behavior of Materials (1999) ISBN 0 13 262817 1] This nonlinearity is… … Wikipedia
