Abstract

During the design process of a new component, it is necessary to investigate its resistance to fatigue. Fatigue life assessment techniques can use experimental and/or modeling approaches. Conducting fatigue experimental test is time consuming and in most cases expensive. On the other hand, modeling approaches are fast and economical. However, there is still a need to calibrate a model to experimental finding before conducting parametric studies on fatigue performance results. In most cases fatigue life assessment is conducted in conjunction with finite element methods. The model of a component is developed to calculate the stress/strain distribution. Because fatigue life assessment is very sensitive to the stress/strain used, it is very important that the finite element model results are as close to the physical test results. The objective of this project is to develop a methodology of combining finite element modeling with experimental result for the fatigue life assessment of an automotive component. In developing the finite element model, it is necessary to make simplifying assumptions with regards to the material behavior, boundary conditions and loading application. Generally, these assumptions lead to discrepancies between the FE results and experimental test. This research focuses on developing a methodology to construct a reliable finite element model that reproduces the observed behavior during the experiment despite the simplifying assumptions.
