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.
