SC28 – Surface Crack at Offset Hole in Plate with Broken Ligament
o These univariant weight function SIF solution are for corner and surface cracks at
a hole in a plate with one of the net sections completely broken through and are
extensions of TC19.
o These crack cases can be used to describe a continuing damage scenario after the
short ligament in the TC13 crack case is broken through and a corner or surface
crack initiates at the opposite side of the hole. The broken ligament is represented
by two parallel edge surfaces with an infinitesimal gap. Stresses can be applied as
remote tension/in-plane bending or (un-cracked) crack plane stresses.
