Residual stresses are the stresses that retain inside the part after removal of loads. These stresses are known to substantially affect performance of a part in terms of service life and response to various kinds of loads. Determination of these stresses has been a challenging issue. Especially in novel Incremental Sheet Forming (ISF) process, no analytical approach has been applied to evaluate these stresses. This study presents an approach to evaluate residual stresses in the ISF parts. The distribution of residual stresses was determined and verified for rotational parts. It was found that the magnitude of stresses reduces as the radius and height of part increases. Further, this happens in a non-linear fashion. Also, the stresses are compressive in nature on the inner surface of part that will derive the improvement of fatigue life of the deformed parts.
