Abstract:  
Academic Study by Dr. David Kirk INTRODUCTION It would be very desirable if shot-peened components could have a uniform coverage of indentations. Unfortunately this is impossible to achieve. As a shot stream passes over a component's surface it induces non-uniform coverage. This is due to the variation of the indent ratio, Ar, that the stream imposes. Coverage is the effect that is caused by a particular indent ratio.
