Finite Element Analyses and Experimental Testing of Hybrid Composite/Metal Joints Subjected to Fully Reversed Flexure Fatigue Loading
Abstract
The goal in this research is to accurately assess the fatigue life of hybrid composite/metal connections focusing upon bolted joints used in removable panels. Experimental testing was performed in flexure fatigue as part of this effort and is essential for fatigue life evaluation. In addition, analytical studies were performed using finite element analysis. Existing finite element modeling software offers a robust method for assessing the structural integrity of proposed hybrid connections. Ansys, a finite element modeling program, was used to study the response of two hybrid connection configurations subjected to fully-reversed flexure fatigue loading. A through-the-thickness stress investigation at critical locations in the connection was developed. Variables in the hybrid connection were altered in a parametric study and effects on flexibility and stress were observed. Through the use various models, a method for predicting the fatigue life in hybrid joints is proposed.
