Influence of interface transition zone on effective elastic property of heterogeneous materials with an artificial neural network study

In this study, the influence of interface transition zone (ITZ) on elastic properties concrete and rock like heterogeneous materials is investigated. Direct simulations a representative volume element are realized by using fast Fourier transform based method obtained results used as reference solutions. Some widely analytical homogenization models evaluated comparing theoretical predictions with Based evaluation, an artificial neural network (ANN) model constructed in order to improve models. The proposed ANN trained, tested validated against solution. Its efficiency good accuracy clearly demonstrated.
