Year: 2025
Type: article
Abstract: Despite significant advancements in understanding the effects of hardening modes, particularly shot peening, on the stress–strain state of materials, the determination of residual stress remains a considerable challenge, especially when temporal factors are involved. Conventional methods for measuring residual stress are often laborious and costly. In this study, the modeling of residual stress formation and the calculation of manufacturing-induced residual strains are performed. This article’s objective is to investigate the redistribution and formation of residual stresses in the surface layer of components, along with the resulting deformations using shot-peening samples. This objective is realized through the incorporation of the concept of initial stresses. The findings demonstrate the effectiveness of finite element analysis in predicting residual deformations in complex components such as blades, disks, and other geometrically intricate aircraft engine parts. The proposed approach offers a faster and more cost-effective alternative to conventional residual stress evaluation techniques.
