Abstract

This paper presents the results of eigenstrain analysis in non-uniformly shaped shot-peened 17-4PH stainless steel samples. The finite element models are established for inverse eigenstrain analysis of slices and bulk conical samples. It is shown that the elastic strain distributions and relief are directly related to peening intensity and sample shape/thickness via the underlying permanent strain, or eigenstrain. Thus, the effect of the peening treatment is best described in terms of the induced eigenstrain. The proposed framework for predictive modelling of residual stresses in non-uniformly shaped shot-peened materials allows efficient reconstruction of complete residual stress state, and provides an excellent basis for developing predictive tools for in service performance and design optimization.
