Residual Stress

 

the stress that remains in a solid body once all external forces have been removed. A residual stress develops in a solid when the external forces elicit both elastic strain and plastic flow.

residual stress

A stress that remains in an unloaded member after it has been formed into a finished product, such as that induced in steel shapes by cold bending, cooling after rolling, or welding.

While in the manufacturing processes of aluminum alloy forgings especially in the quenching process, high residual stresses are introduced inevitably, which cannot be thermally relieved while maintaining the alloy's favorable mechanical properties, and cannot be relieved by traditional pre-stretching as aluminum plate due to their complex structure.

Residual stresses are produced by processes that change the shape of the solid causing nonuniform plastic deformation in the solid (rolling, forming operations), by processes that produce high thermal gradients in the solid (welding, casting), or induce localized phase changes (martensitic hardening) [1].
Based on these test results and the inverse analysis techniques, the tensile strength and the residual stresses are defined, which can be further used for the strength, deflection or crack width analysis of SFRC members (Dupont 2003; Slowik et al.
