interface modelling of a bi-layer system to predict the delamination profile using ABAQUS

Hi everyone,

         I am

doing the similar project like what you did. My project is to predict

the delamination pattern in the interface of a bi-layer system

(substrate and overlay) using ABAQUS. Substrate is made of normal

concrete and overlay is made of High-Performance concrete. Delamination

is induced by maintaining high temperature (say 95 F) in the enclosed

room due to which different materials used will absorb different

temperatures and because of this difference of temperature in two

layers, shear stresses are developed at the interface due to which the

delamination occurs.

My questions are: What are the properties required to input in ABAQUS?

How to model the interface?

How to input the temperature loads?

Any suggestions will be appreciated. Thank you very much Sir.
