composite modelling

Hello all,

I am doing my masters thesis on composites.Its material with cnt yarn embedded in steel.I modeled cnt yarn as solid and matrix as soilid and glued them together.the values of youngs modulus for yarn is lower than that of the matrix.I obtained some results on stresses bt the maximum stress is seen along the tip tranverse to the ysrn axis?I hope the stress should be around the yarn.

I am using ansys 13 for the analysis.Could you please help me in soving this problem???
