The stress in a body resulting from some previous forming and/or heat treatment operation. Found for example in castings, weldments and cold formed parts.
Stresses induced by set removal, shot peening, cold working, forming or other means. These stresses may or may not be beneficial, depending on the application.
Stress mechanically induced by such means as set removal, shot-peening, cold working, or forming. It may be beneficial or not, depending on the spring application.
Residual Stress: Stress remaining in a structure as a result of thermal or mechanical treatment or both.
An internal stress not depending on external forces resulting from such factors as cold working, phase changes, or temperature gradients.
Stresses that remain within a body as a result of plastic deformation.
The stress which exists in an elastic solid body in the absence of, or in addition to, the stresses caused by an external load. Such stresses can arise from deformation during cold working such as cold drawing or stamping, in welding from weld metal shrinkage, and in changes in volume due to thermal expansion.
Stresses incorporated within a spring by coiling, compressing to remove set, shotpeening, cold working or induced by heat treatment.
Macroscopic stresses that are set up within a metal as the result of non-uniform plastic deformation. This deformation may be caused by cold working or by drastic gradients of temperature from quenching or welding.
Stresses that are generated and exist in a section due to a manufacturing process.
the effective stress generated in a thawing soil if no volume change is permitted during thaw.
Residual stresses are stresses that remain after the original cause of the stresses (external forces, heat gradient) has been removed. They remain along a cross section of the component, even without the external cause. Residual stresses occur for a variety of reasons, including inelastic deformations and heat treatment.
