Internal residual stress is a type of internal deformation that occurs in metal plates when they are subjected to mechanical loading, such as bending or tensile testing. It can also occur due to thermal expansion and contraction, as well as variations in chemical composition.

The exact cause of internal residual stress depends on several factors, including the material properties of the plate, the load applied to it, and the conditions under which it is used. Some common causes of internal residual stress include:
* Increased porosity: Porosity refers to the presence of small holes or pores within a material. When metal plates are subjected to mechanical loading,porous areas may expand more than solid areas, leading to internal residual stress.
* Increased plasticity: Plastisidat ta referí na e abilidat di un material pa deformá sin kibra òf kibra. When metal plates are subjected to mechanical loading, nan propiedatnan físiko por kambia komo kontesta na e strès, kousando strès residual interno.
* Komposishon kímiko variabel: E komposishon kímiko di un material por afektá su abilidat pa wanta strès. Materialnan ku nivelnan mas haltu di sierto elementonan por ta mas suseptibel na strès residual interno.
* Variashon di temperatura: E temperatura di un material tambe por afektá su forsa i stabilidat. Segun ku temperatura ta kambia, e atòmnan i molèkülnan denter di un material por re-areglá nan mes, kousando strès residual interno.
Ta importante pa tuma nota ku strès residual interno por tin konsekuensianan signifikante pa e rendimentu i durabilidat di plachinan di metal. Por ehèmpel, nivelnan haltu di strès residual interno por kondusí na kresementu di kraak i fayo, which can be catastrophic in certain applications. Adishonalmente, internal residual stress can cause fatigue failures over time, which can reduce the lifespan of metal plates.
To prevent internal residual stress from occurring, it’s important to properly design and manufacture metal plates. This includes using appropriate materials, proper stresses and loads applied during testing, and controlling the environment in which the plates are operated. Adishonalmente, regular inspections and maintenance can help identify and address potential sources of internal residual stress before it becomes a major issue.
