Abstract
Fatigue crack growth rate (FCGR) was studied in SMAT- exposed AISI 304LN stainless steel. Compact Tension (CT) specimens were taken for this study. Specimens were exposed to SMAT at various exposure timefor generating varying compressive residual stresses and FCGR study was done on those specimens at R=-1. It was seen that exposure to SMAT, produced micro-cracks within the material that increased the FCGR of the material with increased exposure time.
