crack-tip stress field

I am a post graduate student in mechanical engineering,
as  a part of curriculum  I am doing my thesis  work on fracture mechanics. My thesis title
is “ STUDIES ON CRACK-TIP STRESS FIELDS IN HOMOGENEOUS SOLIDS”.I  have modeled crack-tip using modified
boundary  layer. I have analysed  S22 (tangential stress) for T/σ=0, T/σ=0.34
&  T/σ=+1.my values are matching with
N.P.O’DOWD and C.F.SHIH for T/σ=0 and T/σ=0.34. But for T/σ=+1 the values of
S22 are coming for less than HRR
values.

Small-scale yielding conditions are enforced  by not allowing  the plastic size zone  rp

 to exceed 0.1R. I  am not able to decipher this mystery. I am
using ABAQUS to solve my model. ABAQUS input file and result sheets in EXCELL
are attached with this mail. i seek your valuable advice to overcome my
problem.

 i am not able to attach abaqus input file . 

Thanking you
