Economical determination of residual stresses in castings

Residual stresses are those stresses which exist in some machine member, also when there are no external loadings or temperature gradients. Production processes favor by and large creation of residual stresses (for example casting, welding, machining, heat treatment) by capturing residual stresses within the work piece. After complete cooling off of the casting there are residual stresses which equal sum of stresses having different origin. If these stresses exceed tensile strength of the machine member, cracking and distortions of the casting in production or service will take place.
