RETRACTED: Computational Investigations of the Impact Resistance of Aluminum–Epoxy–Laminated Composites

In this article, Charpy impact resistance of aluminum–epoxy–laminated composites in both crack divider and crack arrester configurations has been investigated. In both configurations, an analytical investigation has been carried out to evaluate the effects of layer thickness on impact resistance of the specimens. A model based on gene expression programming for predicting impact resistance of the specimens has been presented. To build the model, training and testing were conducted using experimental results from 126 specimens produced of two basic composites. The used data as inputs of gene expression programming models are arranged in a format of seven parameters that cover the thickness of layers, the number of layers, the adhesive type, the crack tip configuration, the content of SiC particles, the content of methacrylated butadiene–styrene particles, and the number of test trials. According to these input parameters, in the gene expression programming model, the impact resistance of each specimen was ...
