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.

In the previous paper [1], the authors have demonstrated a mechanics-based approach to predict residual stresses and effective plastic strains in small-radius cold-formed sections, considering the effect of change in the corner radius-to-thickness (r/t) ratio and the shift in the neutral axis for an elastic-perfectly plastic material.
It has been established that a numerical simulation method is a cost-effective technique to evaluate thermal history, evolution of residual stresses and distortions during the laser cladding process, which therefore make it possible to optimize process parameters without physically utilizing the technology.
It is well known that almost all thin films, produced by the various deposition techniques, have residual stresses. Residual stress that develops during thin film growth is critical issue for many applications.
Based on the stress values at the nodes and the distance between the nodes, Figure 4 is obtained; this figure shows the distribution of residual stresses calculated from the simulations.
The localized heating and melting nature of welding or metal 3D printing inevitably generates high tensile residual stresses. A longstanding manifestation of the detrimental effects of high tensile residual stress has been the hydrogen induced cracking (HIC).
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.
This study attempts to quantify residual stresses with varrying coating material composition and drop size of spray.
