Hi,
I am simulating failure of concrete in tension and compression on a concrete representative element volume. I have modeled mortar matrix and aggregate (inclusion) separately i.e my model consists of two material and assumed them as perfectly bonded. My question is, if I add interface zone between matrix and inclusion how will it effect my overall failre or can I neglect inerface.
With Warm Regards

re: Effect of interface
Dear Gouse:
I am a newbie in this field of composite concrete and even writing a response
to a blog, however I am dealing with magnetoelastic composites, which has
similar problem.
Anyway, apart from that recently I have attended a conference in which one
research group has done some analysis based on the composite configuration.
They have used Mori-Tanaka approach with a numerically calculated Eshelby's
tensor to solve the electrostatic modulus in terms of the constituent modulus
to further estimate the effective modulus. You may look at the abstract
and paper ( which will come out in a months' time). This may be a
different topi, but you may take advantage of the approximation
technique.

effect of interface
Hi Kamlesh
Thank you for suggstions, I will go through your reffered papers, hope they will be useful. But my doubt was how can failure behavior changes with a weak interface.
