The process optimization module also selects and optimizes the heat treatment and machining processes to minimize residual stresses
, distortion, and manufacturing cost.
Contract notice: Provision of a nano-indenter and a system for measuring residual stresses
by X-rays for the University of Tours.
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.
In this article, the effect of residual stresses
and interfacial adhesion on the RCP performance of bilayered PP/PE100 pipes is investigated.
The hole drilling method has been used for many decades, using strain gages to measure the change in surface shape around the hole as a result of the removal of residual stresses
in the hole volume.
Characterization of Residual Stresses

The Lawrence Livermore team led by mechanical engineer Amanda Wu developed a method to measure the residual stresses
in parts manufactured via powder-bed fusion.
In arc welding, controlling the angular distortion without increase in residual stresses
is a major task.
European Conference on 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) .
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.
The level of residual stresses
is an important quality attribute of extruded pipe.
