Fracture mechanics in ABAQUS

Hello Everyone,

I am new in this forum.I am trying to model Fibre reinfored Polymer
fracture in ABAQUS . But, In website I could not find any example for
that.I have done fracture model for isotropic material such as
Alluminium using Contour Integral.But, for this FRP I am being unable to
model   it.What should be my consideration (different from isotropic)
using this contour integral.I want a tensile matrix cracking or
matrix-fibre interface cracking or fibre cracking. Please help me in
this regard.

Thanks & Regards,

Dear all,

I am a M.Tech Student doing research on Fracture Mechanics of Fibre Reinforced Composites using XFEM in ABAQUS.

To
achieve the goal, I started from Crack Initiation and Propagation for
isotropic material in ABAQUS using XFEM following this manual
http://www.scribd.com/doc/102150619/Frac-l09-Xfem.

It has two case:

1. Crack initiation and propagation
2. Propagation of an existing Crack.

For the first case, Maximum principle stress criterion has been used
and maximum principle stress has been set as 22e6. In result, in the
crack tip stress become about twice this maximum stress.But,  no crack
has been initiated.

For the second case, crack is propagating for some mesh size and crack is not propagating for some mesh sizes.Result is not converging uniformly with mesh size variation.

I am begging for your kind attention to help me in this regard.

Waiting for your kind advice,

Thanks & regards,
