Effect of interface

Thu, 2009-03-19 11:53 - Gouse

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

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.

Hope this may help you.
