A novel weight function for RMS stress intensity factor determination in surface cracks [PDF]
, 2010 This paper discusses the problem of stress intensity factor determination in surface cracks. In particular, the concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of semi-elliptical surface cracks.
