sisäjännitteet
Sisäjännitteet, often translated as internal stresses or residual stresses, refer to stresses that exist within a solid material or structure in the absence of external forces or loads. These stresses arise from various manufacturing processes, thermal treatments, or mechanical deformations. They are essentially a self-equilibrating stress system within the material.
Common sources of internal stresses include welding, casting, forging, machining, and heat treatment processes like quenching
The presence and distribution of internal stresses can significantly impact a material's mechanical properties. Tensile residual
Measuring internal stresses can be done using various non-destructive and destructive techniques. Non-destructive methods include X-ray
