- This decay of contact force, a natural consequence of the structure of all metals, is called stress relaxation. Stress relaxation is the time dependent decrease of the stress in a metal under constant strain, such as in a beam with fixed deflection.

In materials science, stress relaxation is the observed decrease in stress in response to strain generated in the structure. This is primarily due to keeping the structure in a strained condition for some finite interval of time hence causing some amount of plastic strain.

What is stress relaxation in Materials Science?
There are two time constants for relaxation of polarization, one for relaxation at constant electric field (dielectric relaxation of the displacementD!) denoted by τE, and one for relaxation at constant displacement (conductivity relaxation of the electric eld E!) denoted by fi τD.
In continuum mechanics, stress relaxation is the gradual disappearance of stresses from a viscoelastic medium after it has been deformed. Dielectric relaxation time. In dielectric materials, the dielectric polarization P depends on the electric field E.
Stress relaxation is a technique through which we can simulate the real-time working conditions on seals by maintaining desired temperatures and pressures. In modern stress relaxation equipment, both tensile and compressive tests are performed by isothermal conditioning or temperature cycling.

Jan 1, 2024 · Stress relaxation is a thermomechanical phenomenon where elastic strain is slowly converted to plastic strain, even at stress levels far below the yield strength. Because contact force is generated only by the elastic strain and not by plastic strain, stress relaxation results in a continual decay in contact force.
