... J-2 Crack Shape and Crack Depth The shape of the crack and the depth of the crack have the following relationship, as shown in Figure J-1: ,max 0 ,max cn c c c d d w w d         (J-3) where 0w is the width of the crack at the surface in mm; ,maxcd is the maximum depth of the crack in mm, cd is the depth of the crack; and cn is the crack depth exponent.
