Inverse/genetic method and its application in identification of mechanical parameters of interface in composite

Abstract

In this paper, an inverse/genetic method for interfacial parameter identification is developed. The interfacial parameter identification process can be converted into an inverse approximation problem using the method which includes finite element method and genetic algorithms for searching solution. Based on the interfacial failure information obtained from experiment, the inverse approximation procedure identifying interfacial parameters is constructed by taking the advantages of genetic algorithms over traditional gradient-based search methods. The study indicates that a good prediction with relatively high accuracy of the interfacial parameters of real composite can be achieved with the proposed method. It seems that the proposed method is promising in solving a wide range of parameter identification problems in robust way.
