Numerical study of residual stress fields after double-sided symmetric laser shock peening of blade edge

Fracture and Structural Integrity
This paper deals with numerical modelling of the residual stress field formed after laser shock peening of a thin blade edge from TC4. It is shown that the application of double-sided symmetric laser shock peening is an effective way of treatment, as it ...
