For my
graduation project I’m working on a model to describe cracking behavior. For
this model I want to model a fibre-epoxy interface, see the attached figure 1
(due to symmetry only a quarter is modeled). The fibre part is modeled with
lineair elastic material. The epoxy part is modeled with CPS4 elements, with
elastic behavior and MAXPS damage (damaged evolution included). The connection
between the fibre and epoxy interface can be modeled with both a cohesive
surface and cohesive elements. However
XFEM, Damage Evaluation
Dear Colleague
I am modelling a 2D three point bending to analysis the crack propagation , i have a question in the part of damage evaluation, does anybody know what is different between, B.K , power law and mod.independent? means when we select one of them. Thanks

Hi
iMechanica,
For my
graduation project I need to model the cracking behavior of a concrete beam in
bending (To simulate delamination of Steel Reinforced Polymer).
However I’m
relative new to FEM, I’m using Abaqus 6.10 (and have 6.11 available).
To get used
to the modeling of cracking behavior I started with a simple example, as described
in:
Alfaro, M.
Suiker, A. (2010) Transverse Failure Behavior of Fibre-epoxy Systems, Journal
of Composite Materials, Vol. 44, No. 12/2010.
ABAQUS - XFEM

i am using XFEM in a 2D analysis (plate under uniaxial tension) and would like to get the SIFs at different crack lengths to compare with published data for verification before i start performing crack propogation analyses.
My problem is, history outputs are not available for crack growth in XFEM only static cracks (at least from what i read).
Ideally, i would love to get the SIFs as they change through the crack propagation.
Anyone have any ideas on this?

please help me on selection of enrichment function for modeling of hole
in XFEM and how to added the additional degree of freedom to the
enrichment nodes and also on implementation of XFEM please help me
