At the 1520 MPa strength level, it is found that the KIC value is 66 MPaVm , while
at 2070 MPaVm KIC drops sharply to 33 MPaVm (Fig. 8.17). For a large sheet the
stress intensity factor is determined from Eq. 8-22, where the design stress is ...
strength level 66 MPaVm =760 MPaVra 2a = 4.8 mm which exceeds the
minimum flaw size requirements. At the 2070 MPa strength level, however, 33
MPaVm = 1035 MPavW 2a = 0.65 mm which is five times smaller than the
minimum flaw ...
Consequently, Ke (or /l/c)««110 MPaVm . The stress intensity factor was then
estimated by measurement of the shear lip depth (about 0.8 mm) along the
surface of the hole (Fig. 14.8). From Eq. 14-1 1 K2 shear lip depth « lit a 2 y 8X10"

This is one of the best textbooks on physical metallurgy. My preference is for Dieter's book, but that is because it was the textbook for my physical metallurgy course in graduate school. Hertzberg's book is more modern. Read full review
