Surface stress concentration analysis of shot peened aluminium alloys Chapter in Scopus uri icon

Abstract

  • Fatigue limit for surface crack initiation on shot peened Aluminium Alloys resulted to be determined by surface residual stress and stress concentration, according to the magnitude of the applied stress. The effect of surface roughness considered as micro-notches (dents) has been analysed by using the Vallellano and Navarro's formulation. It was also determined that the stress gradient associated to those dents dominates over the closure stress effect. © (2010) Trans Tech Publications.
