Abstract

Highlights: A cross-sectional linear indentation coverage method is presented to theoretically analyze shot peen forming process. Simple explicit relations are derived to describe the deformation behavior of plates in shot peening. The depth and coverage of indentations are proven to be the two essential factors that affect the deformation behaviors of the shot peened components. Abstract: Shot peen forming process is a complex process in practice, and there are few analytical models published to facilitate analysis and design of the process. An analytical model of shot peen forming process is established by using cross-sectional linear indentation coverage method in this paper. Deformation of narrow-strip shot peened samples is examined by considering single indentation effect together with its distribution along a cross sectional line. Mathematical expressions are formulated to describe the deformation behavior of samples undergoing simple bending and simple extension. It is proven that the depth and coverage of indentations are the two essential factors that affect the deformation behaviors of the shot peened components. Verification shows that theoretical calculation agrees well with experimental observation. Graphical abstract:
