sisäjännitteiden
Sisäjännitteiden, or internal stresses, refer to stresses that exist within a material or structure even in the absence of external loads. These stresses can arise from various sources and significantly influence the material's behavior and performance.
One common cause of internal stresses is thermal expansion or contraction. When a material is heated, it
Another source is phase transformations. During changes in a material's crystalline structure, volume changes can occur,
Internal stresses can also be present due to the presence of defects, such as voids or inclusions
The presence of internal stresses can have both beneficial and detrimental effects. In some applications, like
