Abstract:
The mechanics of shot peening is considered from the perspective of the Hertzian theory, and the requirement for modelling with theoretical/numerical methods are discussed.
The modelling scheme developed enables the investigation of single and multiple indentations and provides predictions of the residual stress field and depth of work
hardening. The results have shown that the strain hardening behaviour of the target material influences the induced residual stresses, and incomplete coverage induces
beneficial compressive residual stresses or in some cases tensile, that explain the detrimental effects that have been observed in cases of poor coverage.
