Comments on “Approximate Green’s functions for singular and higher order terms of an edge crack in a finite plate” by Xiao and Karihaloo [Engng Fract Mech 2002;69:959–981]

T-stress dependence on the loading along the crack face is an important topic in fracture analysis. It is found that a statement for T-stress evaluation in Engng Fract Mech 69, 959–981 (2002) is incorrect. A rigorous derivation for T-stress for a semi-infinite crack is presented.
