Abstract:
Increasing coverage as shot peening progresses invlves multiple impacting. Over-peening will induce cracking and reduce fatigue and corrosion-fatigue performance. Equations
for multiple impacting [Avyaneh MY 'Fundamental Aspect of Shot Peening Coverage Control Part One: Formulation of Single and Multiple Impacting' ICSP6] is used here to
demonstrate, quantitatively, how the proportion of the total coverge due to specific numbers of impacts changes as coverage increases. These changes have also been
simulated using computer-generated drawings involving random-number coordinates for circular
centres. The effect of multiple coverage on fatigue performance is discussed.
